Rule Nr. 1: Trolls will always find a way to troll.

Rule Nr. 2: The Multiplayer itself is the greatest potential for trolls.

DotA 2 has lots of stuff... LOOOOOTS of stuff that can screw your team up and allows extreme trolling. Tiny can throw random nearby allies to a destination, Storm Spirit can say YOLO in a teamfight and quickly move away with his ult (or into the enemy base), there's Divine Rapier which gives +300 damage (and despite needing 6.3k gold it's the most cost-efficient damage item... with no other stats, nonetheless) but will be dropped on dead and can then be picked up by enemy heroes. And still, many people say that DotA 2 is the superior game (you could nitpick and it's generally better to wager the pros and cons against each other than just say "it's better because of reasons". Although I'm slightly favouring DotA 2 right now. Just slightly).

When making a large-scale competitive game (and by "large" I mean anything with 2+ players per team), you will have trolls, no matter what you try as a designer and programmer. You can only do one right thing, then: Make the in-game awesome even if it can be abused (because it is already abusable that you are a character you, but no other player can control) and punish the trolls by out-game measures. Trolls are breaking character in an RPG-inspired environment, so why shouldn't the Gamemaster/s utilize out-of-game punishment while trying to come up with great ideas?

tl;dl TROLLS WILL BE TROLLS NO MATTER WHAT SO MAKE THE GAME AWESOME CRUISE CONTROL!
