It's LoL lingo for AD(attack damage) Carry. Basically heroes that do most of their damage through their normal attacks rather than skills. The other type of carry in LoL is AP carry, spell based carries. The distinction was made because originally in dota, there was only one type of carry, the equivalent ADC, since spells didn't scale with gear.What's ADC? I don't speak MOBA
Out of all the online communities, mobas are generally accepted as the worst, closely followed by console FPS and shit like that. The Duning-Kruger effect is at its max potential when you play a game that forces you to play in random teams for the whole duration of the game(quitting tends to be heavily discouraged in all of them) and obviously in the usual anonymity of internet.I never played a MOBA before HotS. I like it pretty well but goddamn some people take this seriously. I get competitive matchmaking being high pressure but there are some serious asshats in quick match mode.
