So when I started playing Coil I didn't like him. R is switching?? Q is tethering??? No aoe buffs???? What?!?!?!? But I kept on using him. I saw two dash moves (one with i frames) with cooldowns below 3s, other crazy low cooldown moves, and had hope. I'm happy I stayed using him because he's OP.

Gravity is your best damage dealing coil. M2 lets you get way above the opponent, easily comboing to aerial E and possibly landing a 45 dmg combo. Trying to chase a single target and land the double aeriel E combo is decently difficult, I've noticed it's easier to land in a large brawl. Grounded E is also pretty good, great when you dash in to a crowd and catch them by surprise. A or S buff can be GREAT for escaping to a higher level on certain maps, and after than you can switch to heal coil and heal crazy fast

Speed is busted. Two dash moves, one of which deals damage, another of which has I-frames and buffs style meter if dodging an attack. Speed is CRAZY good at just popping right up to an opponent's face that isn't expecting it and quickly eliminating them. Any class with bad or no mobility simply cannot escape. Also, grounded E goes crazy far BUT aerial E has a shorter cooldown and a shorter dash. This is great, it lets coil choose how far they want to go, possibly mixing up opponents. More options is always good

Heal is my favorite stance. M2 is a great poking tool that I just use whenever it's off cooldown. E is crazy. It heals SO much to allies, and the 75% dmg reduction can sometimes give you a net positive healing along with the passive healing. Using another ability also instantly de-activates E, which is a simple mechanical thing that I really like.

I usually default to tethering with heal on a DPS character or a healer (like medkit who really needs it), and occasionally switch healing to a low health ally. I tether with speed coil on rollout, sometimes for allies who need it to run from someone trying to kill them, and banhammer who can thrive with a speed buff. I realize I don't use grav tethering, but after some thought about it, it can be useful for rocket so they can shoot easier, and great for katana for higher air-stalling.

Fusion is busted. Crazy high damage, crazy high healing. Since it has every buff at once, at S rank you're just flying around your opponents, and cashing out with M2 makes you even stronger. When landing the grab, you can easily do a ~120+ dmg combo.

So, you basically play like a brawler / assassin half the time (but a brawler / assassin with crazy good sustain, weaving in and out of an opponent's range while hitting them, and blocking / dodging any attacks while in range), and the other half you go to an ally, healing them and physically protecting them by standing between them and an opponent while using heal E. HES SO FUN!!!
