Those Skarner buffs on PBE
The title speaks for itself. I'm glad that you guys are remembering everybody's favorite Brackern (I'm just gonna pretend the lore changes didn't happen), and the mana cost reduction on his Q and making his E's CD lower as you rank it will give him a little bit of late game power that he will enjoy.
Only thing I am concerned with is you are forgetting that Skarner can be optimized (with items) for damage as well instead of just as a tank and I figured that maybe the Bonus AD and AP Scaling on his Q could be increased? It seems you want to target changes toward him to affect him later in a game, well I imagine this would help much (his Q really doesn't do much damage later in the game).
It would also help to alleviate the current problem of building damage on him but not actually gaining much from it (the only damage items he does well with are on-hit effects), thus making Tank Skarner the only option (usually being Triforce -> Tank Items).
I'm also happy to see buffs to other jungles that many thought were forgotten, so I hope to see the changes on PBE ship to live in a few weeks. Keep up the great work Riot!
