Taric change
His E duration and damage should be the same, and be 2 second stun with same damage, far or close, i really find it weird that Taric Stun duration get 0.1 sec per level and damage is increase when closer to the target, it make really no sense at all. Maybe increase the cooldown by a few second as compensation, but it need a change.
EDIT: Instead of increase the duration, maybe increase the missile speed, because really often people have the time to either flash/dash/blink and just go so far away and the stun being so short, give no time to reach the target and end useless.
