Just discovered a really cool tip for melee fighting hulks
Fight them near bodies of water (pools, rivers, etc.)
When you get launched by a hulk, only a very small amount of damage comes from the actual punch. The overwhelming majority of the damage and pain occurs when you actually hit the ground. But when you get launched into a body of water, all you have to do is climb back out and continue fighting
My character got launched into a river while fighting a hulk, and exited the river to continue fighting with only 3 pain, minor torso damage, and no damaged clothing.
EDIT: Be careful not to drown in the process. This almost happened while I was fighting a second hulk.
