Why can't you just admit your mastery rework was an awful idea?
By far, most builds revolve around different ways of applying damage. "Do you want to nuke them in half a second or over a short period of time?" Or absurd bonuses like free spells every 60 seconds (no mana cost). Attempting to force diversity doesn't work; there's an optimal path for each unique champion. All you've done was sped the game up even further, despite a vast majority of your community complaining about it. The game doesn't need more damage, especially mages.
(Leblanc 2.0), unlike say 
who have the obvious weakness of lack or mobility and (at least in Velkoz's case,) unreliable cc.
.
needs to be removed, as it's basically a better 
unless there's a 
worth noting and grants defensive stats and cdr without sacrificing damage or lifesteal. 
should be reverted to its old unit collision passive considering it offers true damage reduction and I agree that's ridiculous, along with 
nerf. 
items need a bit more % armor pen and towers need to deal more damage, so bruisers/juggernauts take some real risk when they dive/fight under tower for extended periods of time. Ffs 
can nearly executed a squishy with nothing but 
and 
for AD and still be pretty tanky. Obviously not enough to survive an entire teamfight, but easily more than enough to act as a pseudo assassin and delete someone in less than two seconds before an auto attack or two despite 20% lifesteal and 50% crit can do them any good. There's plenty wrong with the game; I'm just pointing out a few of many.
Udyr just stuns you and shreds you with tiger stance. (Press the Attack or Lethal Tempo)
Shyvana is tanky and mobile with high damage output. (Press the Attack)
