Formatting with stars because Reddit lists are shit, I'll start for my girl Psylocke:

*Learn pack placement. You are mobile, you don't need to hug healers for health that need to keep your tank(s) and other range DPS alive.

*Don't stealth to engage. Stealth is your escape, dash in or walk in and use it as a failsafe. Only use it as a KS if you sure there won't be a follow up. There are plenty of buildings around on each map and most people tunnelvision in front of them so you won't get seen anyway probably until you shoot at them.

*Aim center mass. Each pellet restores your CD, you want them to hit so headshots are not worth it. 4 two-shot bursts are a kill most of the time and a complete reset on your skills.

*Never ult when people can focus only on stopping your ult, use the chaos of teamfights to jump the back line. Your ult can kill 3 squishy max or 1 tank and 2 squishy, if you get even a kill its worth it. Killing a Dagger for example can totally ruin a team. Keep track of cooldowns on their team so you don't ult and hear a KPOP idol start singing and be like NUH-UH.

*Your combo for heroes 250hp or less: R2 until 2 bursts come out, L2, Dash. Instant kill on them if you land the shots. For my PC bros that's: Normal Attack, Shuriken, Dash.

*Your combo for 275hp: R2 until 2 bursts come out, L2 R2 dash.

*If they are in your melee range (275 and below): R2 for 2 bursts, melee, L2, dash.

*If you are quick with your 180s, double dash is a guaranteed kill but watch how you direction yourself.

*Your target are highgrounds. You do not care about the Strange if there is an MK or Hela on a highground or Punisher in a turret. Let your other DPS deal with tanks and clear their threat.

*Targets in order of priority: Highground DPS > Flanker DPS = Backrank DPS (Hawkeye, Hela) > Healers > Tanks. This doesn't mean just flat out ignore tanks, but your mindset should be this. Also if you can secure a kill on a healer go for it but DPS are your prey and usually much easier to kill than someone like Cloak, Jeff, Mantis and similar.

*Flanker DPS (Panther, Psylocke, Fist, Spidey) are also your top priority target. Their job is to go for your healers and you need to make it difficult for them the best you can. A lot of people don't protect their healers at all, spam Need Heal and lose games because of it , so make sure that they are protected. If you miss out on a kill or 2 to keep your Cloak or Sue alive that will almost always be worth it. You don't need to kill them every time, if you can get them to run back for packs or heals its job done and your healers can breathe.

*Only YOU are your focus. Saying it again for the ppl in the back: ONLY YOU ARE YOUR FOCUS. You do not care if the Spidey is 4/17. You do not care is the MK is 10/10. You care about doing your job right. Being annoyed at ppl will bring your mental down and you WILL play worse. Mute everyone if you have to.

*Do not jump for no reason. I see this all the time, if you jump you are incredibly predictable to track. Jump when you cant be seen to a corner and strafe unpredicatbly when dueling, mix it up.

*Scoreboard is not the problem its a SYMPTOM of a problem. If your healers are 4/11, think why. Look at the enemy team and whats causing it and how you can fix it. Sometimes they suck sure, but a lot of the times you can help change that. Relfect on your own mistakes and how you can learn from them, not someone elses.

There you go lads, happy hunting!

And as always:

Chō no mai o kurāe!
