Resist are cool when they are new, special, and hard to get. As a game goes on, all of those things inherently stop happening. Then they suck.
I remember I had all my resists all well over cap early in pop, since I was rocking like 8 or 9 pieces of aten gear, plus pretty much bis or close every other slot. Had like 5 casters trying to kill me in the bazaar, and absolutely nothing would land outside of malo and tash, and every now and then one of the wizard lures might tickle me a few hps, so they all had to try to club me to death.
It made me giggle, but also exemplifies why resists are so stupid. Cutting out all the casters and saying you're worthless for this fight is not a good way to balance your game. Maybe there's a way to do it better.
