Dota 2

any1 can be the best , the way you play make the game.. and counters ;)... every hero has a counter.. Ember Spirit , shadow fiend are the best for me.

they are equal . data makes the heros all equal in there special way .

It all comes down to personal opinion and preference. If i have alot of experience on one hero, i might prefer it more. And if i never play e.g. Visage, i cant give any feedback if that hero is good or not.
