These problems will never be fixed.
From what I can tell riot has become excessively lazy when it comes to fixing broken things.
: Lane sustain, with untargetability, all 4 abilities I have some form of cc and REALLY fucking high base damage, I'm what we strive for when we think tank.
: I have true damage burst with more speed increases, mobility, counter cc, crit, a slow, and multiple forms of healing on top of my primary build being multiple lifesteal items and some tankiness.
: I have the highest win and pick rate of the entire support roster with the same build every game, and a passive disengage play style based on shielding my allies for ~300-400 hp, while giving them multiple buffs healing move speed and work well with quite literally everything that this game has to offer, I am what we strive for as a support.
:I retained one of the lowwest play rates in the game, until I was deemed worthy of a 4-6 second invisibility time increase. but instead of invis I have camo, but this has little effect as I have 6 more seconds to jerk off in the corner before I spray the enemy team to death. (just reverting this q change would fix me, but why own up to mistakes when you can act like it doesn't exist?) I am what you will think when you hear hyper carry.
: I retain few mana problems, high mobility and burst when all the while having good wave clear and DPS. I am what we need mid-lane.
