It feels like playing with cheat codes.
I get that some people are ok with that, but that always felt like... what's the word I'm looking for... "cheating"?
It's most definitely not in the spirit of D&D where character choices and limitations have consequences.
(And yes, I'm ignoring the whole "don't use it if you don't like it" defense, because that's such an arbitrary defense of poor game design. They've made it a cornerstone of their game design, so not using it is like not using a piece in chess because you don't like the look of it. This is their ruleset and I'm playing their game. But when comparing rulesets, D&D never embraced such an idea for good reason and I think this game is lesser for having done so.)
