Sion buff
Sion has the reputation of being one of the most balanced champs in the game due do not dealing insane damage for a tank and everything in his kit having counter play (a bit too much imo). However right now, for a champ that's suppose to be menacing as a character and a lane bully, well hes not doing much of that. On the pbe for the next patch his W is getting a slight damage buff which it needed since last season but, his Q needs a little tweak. The majority of the top lane roster such as


are easily able to either juke around or cancel his Q altogether while your standing there like a moron and proceeding to be out traded while your main damage ability is just gone, by the time its back up the trade is over and half your hp is gone while your lane opponent is spam laughing at you.
The tweak that I would suggest is to either make his Q slightly longer and or wider (600 units to 650 or 700 units) or slightly less time to full charge/getting the initial knock up (0.25-.5 sec decrease)
