POLL: What do real baseball purists hate the most?

i don't consider myself a real purist, so i wouldn't really know. although i do hate some of these in a non-purist way. ex: wild card format sucks, but i don't think they should eliminate it, i think they should add an extra team and have a wild card playoff before the divisional round. also, it's stupid that one league has the DH and one doesn't, but I think both ought to have it rather than eliminating it.
