The BIG changes to Coast City in the March Patch: You start off with 1k gold, and the passive experience was dropped. Earned gold has been messed around with a bit giving less to early kills and objectives. It may actually be in your best interest not to invade most of the time because the non-junglers would lose out on a lot of gold and exp in lanes at the start while only putting the enemy junglers behind by 30sec at most. The Raider and the Doomsday Guardian now only give radial shared credits. Also the Doosmday Guardian scales harder now and the Device itself does damage and no longer can be used to neutralize relays. Warning, if you take damage while carrying the Doomsday Device, you will have a 3 sec period where you can not fire it.

Now let's talk about the map, and how to play!
First let's take about map layout. There are 2 lanes on the map with a massive jungle. The lanes are guarded by towers; 2 bottom, and 3 top, leading to each base.
Within the jungle there are 3 relays. 1 in each side of the jungle, and 1 at the top middle of the jungle. They are circles that give your minnions extra strength, and you extra gold and experience for each one you control. Relays go into a cooldown period in the last minute of possesion this patch. Your junglers should both make their way to capture your own relay when it unlocks. If you have a solid lead, your team can push and take your enemy's relay. The final relay should have at least 4 bodies there to fight when it spawns the first time. Having Wombo Combo ults can be instrumental for relay control. For example, a Wonder Woman, Joker and Flash ult combo on a relay could be a huge contributor to an easy team annihilation.

The next major point in the jungle is the massive jungle creature that's called the Raider at the bottom. By defeating it (takes 2-3 atleast), your team at the raider recieve credits. This can be used to get an early lead. Both junglers, and bottom laners should be positioned for raider once it spawns.

And the last major point within the jungle is in the dead center, and it's called the Doomsday Device. It is guarded by a very powerful tower, and when you destroy the tower, you can take the device and use it to deal massive AoE damage and/or neutralize an enemy point (like a relay). Your team needs to go this at an opportune time to take it effectively. You must either have the enemy pushed in to their last ring of towers, or just have at least 2 enemies down while your team has high health.

Now it's time for the Meta; 2 jungles, 2 bot, 1 top. This is probably the most effective way to play the map.

Jungling: With the fast camp respawns, the well placed stealth pads, and the fast paced ganking, this map is a junglers paradise. You are also mostly responsible for the raider, relays and keeping the enemy's junglers in check.
My A+ junglers are Nightmare Robin, Atrocitus, Flash, Doomsday, Wonder Woman, Atomic Wonder Woman, Superman, Arcane Green Lantern, and Gaslight Catwoman. Each has their own special abilities which make them deadly efficient in the jungle, and in team fights. Want to learn more about jungling? Here's an awesome guide made for Coast City by SoundByte: https://www.dawnbase.com/guides/soundbytes-cc-jungling-guide-for-beginners

Laning: Grab a tank, or support, with a carry for bottom lane, and a good solo champ for top. If both of your junglers are offensive champs, it is best to have a tank in the bot lane. When laning, let the carry score as many last hits as possible, and pester the enemy laners as often as you can. In the solo lane, just do what you can not to feed (if at a disadvantage), or get pulled into a gank while farming as much as possible.
My A+ carries are Joker, Atomic Joker, Green Arrow, Gaslight Batman, Arcane Supergirl  and Mecha Wonder Woman.
My A+ supports are Posion Ivy, Harley Quinn, Zantanna, Arcane Green Latern, Starro and Nightmare Superman.
My A+ tanks are Arcane Green Latern, Wonder Woman, Atomic Posion Ivy, and Mecha Superman.
My A+ solo laners are Gaslight Batman, Sinestro, Joker, Arcane Supergirl, and Mecha Wonder Woman.

Pre-match: Your team should have  2-3 camera sets. There are no free wards on Coast City. One jungler should have Super Strength to go along with their detonate/meteor drop/consume.  There are a lot of large things to throw on Coast City, and a good car throw in the invade team fight can almost secure a decisive win. Also your tank/support should have healing wave slotted.

When starting the game, your team should decide on invading/protecting, or going straight to lanes. You should have one champ cam the bottom main jungle path  and then join the rest of your team in the top middle stealth pad if invading. Invade the enemy side and take the destroyer if you have the advatage.

Jungling you must rush to level 6 as fast as possible to have your ultimate ready for the teamfight and ganks. After that keep objective control and gank when you feel you can score a pick.

As the top laner score as many last hits as you can, but don't advance your lane too fast. A large wave is most effective to push into a tower. You will do more damage to the tower that way. This personally why I like some blasters top lane. You can zone an ADC out (if they place theirs top), and pick up last hits when a drone is low. You can also unleash combos with no basic attack to draw aggro if you are smart enough and this will cause the enemy to base often.

Duoing bot can sometimes be the trickiest thing on Coast City. You should only have one player farming drones and your support/tank should focus on harass. Two players farming a lane will cause you to advance too fast doing little damage to the tower and setting yourself up for an easy pick. There are four main ganks spots on the bot lane so bad positioning can be deadly. There are an infinite amount of gank spots bot if the enemy jungler(s) don't care about walls. This is why Superman, Atomic Wonder Woman, and a few others can be deadly effective on Coast City.

Here's a revisiting of main points, and stating of simple facts for a review of CC:
1)You start of at level one with 1k gold, and there are no free cameras.
2)Super Strength is super strong in the level one invade team fight.
3)Gank and invade spots are plentiful; bring cameras.
4)Relays are basically the most important points on the map; control them!
5)Don't farm too fast in lane, or you will hurt your lane over time.
6)The Wombo Combo is super strong in team fights over points.

This was just an introduction to my favorite map. Updates are always arriving Soon(tm)!
