I'd like to see the Elder Dragon Buff changed to just straight up "Nuclear Launch Detected". Killing the Elder Dragon would immediately send a 60 second traveling nuke that completely obliterates the enemy base and team instantly. In fact after you lose to the Elder Dragon Nuke you get a 10 game chat restriction, and the game can only be played in black and white.
The nuclear missile can be wind walled though, so there is some counter play. :^)
