enigma is a black hole. that's his lore. that's his ult. people anywhere near where you cast it get sucked towards a spot, take tons of damage, and can't do anything. this hero kinda grows in popularity during teamfight metas and then slowly falls out when the long cooldown becomes too much of an issue. there's a lot of cycles like that. right now pushing is really difficult and takes too long relative to respawns so he's kinda not great at top level. at lower levels the fact that black hole always gives you a chance to turn the game around or seal it in one spell feels pretty strong most of the time. unfortunately, everyone else in the game will be aware of this as well
