In DoTA 2, Leona's ult is a global basic ability, Blitz's pull is point and click, You can get stunned for up to 5 seconds by Ashe's ult, a basic ability can stun you for longer than Morgana's Q as a point and click, you can kill your own minions, supports don't actually interact with the enemy team until later on, and items can negate entire champions until you manage to kill them somehow.
More importantly, the entire concept of having two carries, two supports damaged bots and a mid is disgusting because the supports can literally donate gold by buying scrolls, potions and wards then giving them to the carries, and carries do all the "advanced GG mechanics" that DoTA 2 players just love boasting as Supports just stand in between the two towers in lane, aggro jungle monsters and pull them into lane to make them kill your own creeps, so their carries have less EXP and yours get to farm under tower, and this repeats until laning phase is over. To further rub salt on the wound, supports scale horribly and end up having to buy OP items that replace their abilities because of how useless they become later on, and they just stand back spamming healing potions, buffs, and whatever the hell they can spam.

Yeah I think I'll stick to LoL. If I want to boast totally amazing elitist useless skills that aren't present in LoL, I'd rather go to HoN.
