I play Iron Fist mainly as a brawler against tanks trying to push, and as a defender against divers going for our backline.
Against tanks (whether they're frontline or somehow in our backline), I usually go in with flurry punches right away to force them back.
Against divers or DPS, I mostly stick to basic attacks since flurry punches don't feel as useful there. I'll sometimes hold block to get the extra shield. If I'm full HP, I use it for advantage, and if I'm low, I use it to survive the fight.
I don't usually go for healers since they're deep in the backline, but if the enemy team is split and exposed, I'll pressure them just to force them back. I'm not really expecting to secure kills there, just disrupt.
For my kick, I've heard a lot that it should be saved as an escape, which I try to do. Sometimes I also use it to finish kills or add a bit of burst damage.
My general playstyle is focusing tanks, then immediately switching to any diver I see in my backline until they're gone.
The only characters I really struggle against are Wanda and Thor. Thor especially feels really hard to deal with. Wanda is manageable sometimes, but not if she has teammates backing her up.
Overall, I feel like I'm playing pretty aggressively and moving around the map a lot, but I might be missing something.
Any tips on what I could improve or think about differently?
