@Meddler: What kept Veigar out of the Immobile Mage update?
Veigar's unique, but has several gameplay points that I'd argue aren't very fun.
Firstly, his passive is just "extra mana regen when low", when you could make that far more dynamic. Also, said passive doesn't entirely fit his design of "The Black Mage Yordle", as it doesn't add anything to his "KABOOM" mechanics and just adds some extra resources for him to use (BORING).
Second is that his kit pretty much is just damage, damage, and more damage, with a weird stun/anti-dash mechanic that is now unreliable on its own. Beyond that, he's pretty binary: either get fed on farm (or kills), or do nothing.
Third is that he is both SLOW as molasses, and has unreliable range. This limits the number of compositions he can be in due to his lack of reach.
That sounds like prime material for an update/rework, so why was he kept out of the MYMU?
