Should Amumu's ultimate have a wind-up?
The fact that Amumu's ultimate hits such a large area around him and doesn't have a wind-up means it can end up being oppressive if it's ever on the strong side, and also makes it inflexible to balance changes. I honestly think it'd be better gameplay if Amumu had to spend about 0.5-0.75 seconds winding up before unleashing his ultimate. While that might result in a lot more people Flash-dodging, the lower reliability would allow the ultimate to receive other kinds of power (i.e. converting into a full-blown stun instead of root/disarm).
But this is all anecdote, so I'd like to hear other opinions. Just no shaming, flaming, etc.
