I don't really have a problem with any. I play healer so it's my team that has to do all the fighting. I hate, and I mean hate, being on a team with Mei though. That irritating as shit ice wall that morons keep putting up and blocking off half their team. I'm trying to heal someone and that wall appears and cuts them off. It's hilarious when it happens to the other team but it's annoying as all hell when it's happening on mine. The problem I have is Overwatch seems to have attracted people that aren't very good at video games ... at all. I've seen turrets being built round corners nobody is using, Reapers running in to their death constantly, tanks hiding behind support, DPS that could shoot at the ground and still miss and sooooo many people that have absolutely no idea what objective based PvP is. I've seen videos of people bragging about getting 16 kills, t-bagging every person they killed yet went nowhere near the objectives and their team lost. None of the heroes are annoying to go against, a large portion of the games community are though.
