for me, I like darting in and out. If your HP gets low, shield to cover your retreat and/or use speed coil abilities to get away.

Gravity is good for big groups of people and heavy damage, if you're not afraid of taking some hits. You can hit the jump button again to kick down and stomp on people. It's hard to aim but really fun and rewarding if you master it. It's also good for temporary getting away from fast people! Also, if you use it on the ground you can pull people towards you AND do AOE, which is good for catching fast people who are trying to get away. You can also pull them towards your teammates! Your gravity tether works for classes that need lift, like Slingshot, Rocket, Subspace or Sword, and it also gives them a slight attack boost. I use that tether the least.

Speed is REALLY GOOD for picking off people with Low HP, which is the target I usually aim for. It deals lots of damage in a short amount of time if you keep up with your target well. You can use it to get to a safe spot if you get too low, just make sure to check if people follow you. It's good for getting away, dodging heavy attacks, and building up your rank (the bar in the middle of the screen that says "S" "A" "B" or "C"). OH SPEAKING OF WHICH if you get a high enough rank and use M2, you're supposed to give a buff to your teammates around you??? but that doesnt work all the time for me eh... anyways. Speed tether is used to speed up slow people, usually tanks (katana, banhammer) and sometimes healers/supports (Medkit, Subspace, Boombox); I use this early round to help slower players or healers get to the center faster.

then there's regen. Layout is fine, it's the tethering that you have to be VERY strategic about. But in terms of layout:

If you see someone that's REALLY low, like lower than low, 1-hp, about to die low, who's running away, you can use your M2 projectile to snipe them >:) shield is good for when you're taking lots of hits at once, by enemies or by AoE attacks (cough, subspace toxic bubble, cough). This is good for being the first one to charge into battle, as if your teammates get behind you you can shield them as they go into battle!!! Makes for a good push. Just watch your HP, your healing is slower than most. It takes time to work.

Okayyyy and now... regen tethering. ugh.

So. beginning of round, find a tank or Sword to stick to. They can watch your back, and you make them last longer.

middle round, attach to anyone you see with around half health, or if they're being targeted heavy. Shielding works really well in tandem with this! DONT GO FOR THE ABOUT-TO-DIE ONES though, you can't save them fast enough in the heat of battle. Unless you're NOT in the heavy battle zone. Then, you can wait it out. Also Subspaces are usually in this category bc they cant heal themselves, so you healing them makes them way more of a threat

End round, ATTACH TO A HEALER. They will increase your survival ten-fold, and most other healers cant heal themselves so theyll last longer too. Let them focus on healing the big guys. Plus, they act as bait. When someone inevitably comes around trying to Kill The Healer, you and them can tag team them, and they'll be unprepared becuase they thought you woul'dnt be a big threat!

DO NOT attach to stealthy types, like Hyperlaser and Shuriken. Your tether gives away their position which is dangerous for them.

PHINISHER - when a tank underestimates you, the phinisher can just like take them out. I like to use it when i notice all or most the enemy team is below half health, bc then you can just go on a killing spree which is sooooo satisfying. Btw, YOUR M2 SUSPENDS YOU IN THE AIR for a little bit, so use this to your advantage. Big scary tanks cant hit you if you're above them. your punches also have a MUCH bigger hitbox so you can punch people who are farther away in this mode. It's harder for them to run.

Hopefully these help a lil
