I think Thresh is a great initiator but...what's the benefit of him going to be after his combo is done? At least Taric has his aura when all his CDs are blown but Thresh doesn't seem capable of much after moves. Seems very all or nothing. And the necessity to get corpses to level armor and AP means people will surely pick champs to zone him hard and deny that. The Box is alright but it's not the AoE fight breaker like Amumu or Leona where you're screwed if it lands. You have the option to avoid hitting the walls like you do with Veigar's trap. Looks like it will do well with certain combos but I'm not convinced. The spotlight seems to indicate multi-kills in a team fight are harder to get with Thresh around.

Seem alright but I ain't biting.
