I totally agree.
Having characters as powerful as Hulk (and Thor, Superman, the ludicrous Sentry, etc.) is extremely problematic. When villains are that powerful, they serve as a challenge and a contrast to the heroes. When the heroes themselves have that much power, it's almost impossible for them to be challenged. That was such a problem for Superman that DC tried several times to de-power him so that it was easier to write compelling stories for him. But they always backslid and returned him to previous levels. It's odd that Marvel has fallen into the same habit, and with more characters.
Wolverine started out as an interesting little psycho who would never admit defeat. He has evolved into a less-interesting little psycho who seemingly cannot be killed. Same as for Hulk, Superman and a few others. There is something about those characters that I find very unsettling and unrelatable. Perhaps if I identified with fantasy omnipotence I would enjoy them more.
