I play LoL quite a bit, mostly with friends to avoid the bickering and shit I've heard about, but recently started joining random coop vs AI matches on beginner and intermediate. Not heard any bitching from people on my team, usually they've either laughed along or agreed.
Like yesterday, I was playing as Zilean on Intermediate and suddenly got gangbanged by 4 of the AI champs, and for some reason they all use their Ult at the same time, getting me dead pretty quick. So fast I couldn't use my own ult too survive. xD
I said in chat: "Geez, like a monster truck riding a bigger monster truck who's speeding at 400 kilometers an hour."
They laughed and agreed that AI bots atm, are very trigger happy with Ultimates and tend to do that after they "improved" the bot AI in LoL.
OT: I heard quite a bit about bitching and bickering and all sorts of harrasement about the LoL community before I started playing LoL, which made me not play LoL for ages, but after playing some matches, I haven't really met any of those people. So it might be the same for HoN? Not as many "idiots", to put it nicely, as it seems maybe?
Just my thoughts though, ofc, might be accurate or not.
