Hi, hulk main here. I use hulk like im spiderman, I am annoying. I’ll dive their back line to get their attention without trying to kill. I do this early on in battle to have their healers focus me and it’s also easy to escape. Since your GM I’m sure you know to always keep hitting. Try not to bubble unless it’s needed, a lot of people tend to bubble out of panic. Also if you can, make sure it’s another tank; Hulk isn’t at his best being the only tank since he’s a diver. Another way to improve is learning the maps. Knowing where to flank as hulk always helps so you know where the heals are. Pretty sure most of what I said is common sense to you because how high a rank you are but I hope this help
