I never understood such claims about the playerbases of Dota-likes.
I wouldn't say they're claims, as anyone can prove these claims be simply logging into a Moba Game.
If you played good, like they would expect you to in any multiplayer game, you never received any hate or flame;
That's just simply not true, have you not seen the cesspool of top players and how they run their mouth every bloody second, insulting each other left and right? Case in point, Mobagames are the only genre I've ever seen where congratulating your enemy with a gg is considered a flame and will result in massive bitching and whining.
after all, what could they say about you then?
You didn't pick the champion they think is best, you didn't buy the item they would have bought etc. People have opinions. Opinions differ. Round 1. Fight.
The community in these games, in my opinion, always gave incredibly fine feedback (due to their honesty) and allowed you to improve.
WTF ARE YOU DOING IDIOT, L2P NOOB! Fucking fucktard fucker retard, I hope you die in a fire you dipshit pile of shit. OMG, YOU SUCK!!!!!!!!!! FUCKING REPORT THIS MORON ALREADY!!! DIE DIE DIE DIE DIE DIE OF CANCER YOU FAGGOT AIDS BAG.
Not insulting you there, mind you (really am not). Just providing typical "incredibly fine feedback" Moba style. I hope you can see how this kind of feedback doesn't possess any kind of quality to it. Not sure if you have access to it, the Tribunal in LoL really does show why Moba Games has such a bad reputation.
Absurdity is the main source of entertainment, after all.
Not my kind of entertainment. Not sure if wading through a wall of insults ever was entertaining to begin with.
I do not think people who hate such games just detest the skill requirements.
What skill requirements? I'm sorry but Moba Games aren't exactly hard games. Anyone that has ever played your average RTS Game or RPG will do just fine. So again, what skill requirements?
What is it, exactly, that makes people afraid of these games?
Afraid is pretty much the wrong word for it. People just value their time. The decision is a pretty easy one, do I want a good time or do I want to experience abuse. Hence, the decision to stay away from Mobas. As stunning as it may seem, given how gamers behave in games, people generally don't enjoy insults and verbal abuse.
