That's pretty much my thoughts too. For example: One build I have been working on is a Hybrid Heimerdinger build, which I'm surprised I haven't gotten raged at for yet, and that's probably only because I warn my teamates. The main issue is there are some people who will RAGE UNCONTROLLABLY and FEED because your build or champion choice does not match what the pros do (wanna try a kill lane? Good luck getting that past the thick skulls of some other people). The thing is that this community is very, VERY volatile overall. The half of the people that ARE chill are nice, but it'd be better if everyone was like that.

As for runes/masteries, those are less visible and won't get AS much rage, but I could still see it happening...
