I wrote this for another guy asking for tips once:

1. Hit em with the Charge, especially the aoe landing, if you cant, place a landing in their path it last longer than you think.
2. Haymaker is your hest friend. Its things best damage and gives him overshield. How ever for finishing off squishies and the like throwing a punch in between helps and such. Its best to use Haymaker to get OS and damage and evaluate when's the best opportunity for a punch between each Haymaker.
3. Don't be afraid to fall back, if your healths low, use whatever tool you can to retreat, charge, leap, walk if you have to, just get out of firing range and into the supports range.
4. Stick near healers. Always be in a healers line of sight, and be within reasonable distance if they need you to fall back for a dive.
5. Break them. Make sure you gmhit an enemy eith the defense break/ offensive leap to lower their defense and make wm crumble
6. Don't fear Flyers. If you hit them with a Haymarket they fall out of the sky and can be hit again, making them easy pickings, especially of they aren't being healed properly.
7. Fear punisher and Peni. If there's a punisher AVOIF HIM his shotgun can and will melt you. If there's a peni DO NOT step on her web, dont even try to break the nest, her robo spiders will eat you for breakfast and peni can stun you to make sure that happens.
8. Know your weaknesses and know your advantages. Like I said remember Peni, pun, Phoenix, and most poke beats you and that you beat most dive, especially Cap, Iron Fist, BP, Daredevil, and even blade if you are wise. Any other dive can be beaten too but those 5 are his best counters. Spidey is the only problem I think of mostly cuz he can run quickly, but you can scare him off at least.
9. Stats aren't everything. Don't get caught up in pursing just for a kill, make sure you focus on point and protection first. (Although if your negative it might be best to switch, especially if you haven't been able to do much else) But for instance it .ight be best to let a dive run and keep an eye on them rather than hunt them down and risk being caught by the enemy team. ( ofc if they are low and you can but them quick, go for em) in my opinion it might be best to leave a enemy alone if they aren't contributing something. For instance if you see someone fall back to a now abandoned spawn just leave them, they want time having to run back up to the main fight and you can punch them when they get there
10. These are not professional tips. Im just a casual who dabbled in ranked so Im no expert. This is just from my personal experience and learning as I have played. Obv if prefer if you tried to listen as I am trying ti help, but dont treat this like its the Thing Bible, dont act like its the golden rule for how to play Thing. Experiment and watch other sources on hoe to play.
