Sweet, I’m sitting on 53ish characters atm (severe altititis), and while I never use rest on many builds outside special instances (sappers), there are a few builds where it was used regularly, like my spines/dark brute, elec/storm corr, and human form only PB. I’ve currently got three toons left to hit 50 before I have one of each AT there, and multiple 50s of a couple ATs, so my experience with END in different builds is pretty varied. Some of those endurance issues probably come from how I slot (defense over offense as I hate face planting) and my reluctance to use inspirations outside of anything other games than EB/AV fights, as I consider any builds that have to rely on inspirations as being broken. If you’re sucking down blues all the time because you consider your power sets to be just the cherry topping to your inspiration monster power, then ymmv.
