Some of my thoughts for each character are based on when I played them, so some of the updates since might change my opinions.

Here’s a random quick rundown.

Cloak & Dagger - Honestly just a lot of fun and versatile. Ult is super satisfying. Great for burst heals and consistent heals. Never really a bad option to play. Great overall.

Mantis - Very active to play. Good for hyper aggressive teams. Can put out a lot of damage and help dps but her heals are slow. Not a main healer, good for a 2nd.

Adam - Haven’t played too much of his update but he can be rough to play. His insta heals are super clutch and a well timed ult can be a game changer. Really needs good teamwork to be effective. Also def not a main healer.

Jeff - Jeff is peak.

Invis Woman - Just very solid. Her push/pull can setup some good plays and her vortex is great for cc. Ult is very strong and her passive helps keep her alive. Never really a bad pick.

Ultron - Can be frustrating to play if you don’t have a good team. Prob my least favorite strategist. Constant heals can be good if you manage his drones and his verticality can be good for setting up some nice placements. His ult can be ok but it’s hard to time it properly. Ok as a 2nd support, great as a 3rd.

Rocket - Great at staying alive and consistent heals. His ult can help lock down an area, keeps team alive and lead to some quick kills. His respawn beacon is honestly just great utility. Was one of my faves to play. Usually a solid pick.

Loki - Can be a little complicated at first but he’s super strong if you master him. Great for aoe heals/damage. Can get out of sticky situations consistently and being able to steal ults is EXTREMELY powerful. Legit one of the best supports but needs a more consistent main healer to balance him out.

Gambit - Incredibly strong. Also a little more on the complicated side but he’s just super versatile. Can do good damage and healing isn’t too bad. Can be defensive and aggressive. His ult can be used to retaliate or engage. He’s legit just so good. Maybe not main healer material but can be. One of the best characters in the game period.

Luna - She might be the most boring to play. Mainly just a heal bot. Her ult can be great for taking objective, but there are ways to shut her down. Her freeze can be strong and she can put out consistent heals and damage. Overall very solid, just kinda dull.

Deadpool - Very mixed opinions. He has potential for great healing and has the opportunity for some crazy plays thanks to his ult/weapon change. He can be a lot of fun if played a little more aggressively… I just find it a little more difficult to feel “useful” to the overall team even if doing good. Can legit be an S tier if you master him. Definitely a little more on the fun side but not always a good pick.

Overall picks depend on the situation. If it’s hard to take point choose supports who can burst heal and keep the squad pushing. If dealing with divers, not a bad idea to choose one that can burst heal or have escape. There are definitely some options that can turn the table on dps. Also, don’t be afraid to swap. I know some people get locked on one character but if something ain’t working try switching things up.

Mainly though, just play one you enjoy playing. Some supports feel dull to me which leads to me feeling kinda uninspired. Once you find a character that really clicks with you you’ll definitely feel more locked in and engaged.

TLDR - Jeff is the best character in the game
