Sona W Change
I was just wondering what other Sona lovers would think of this change to W. I have my own reasoning but instead of blathering on about "this is like this because this" and "that is like that because that" I figured I'd let others come to their own conclusions. Please ask questions. I love feedback and welcome a chance to discuss the current state of her W and what (if anything) could be done to improve it as I feel it is a really weak part of her kit right now.
W
COST: 80 / 85 / 90 / 95 / 100 MANA
ACTIVE: Sona heals the two most wounded nearby allied champions (could be herself if one of the most wounded).
HEAL: 30 / 60 / 90 / 120 / 150 (+ 30% AP) (+20/+40/+60 (From ult passive))
AURA: Sona and tagged allied champions receive a shield lasting the duration of the Aura (ends if she switches to another Aura) that is equally divided between all shielded when they are first tagged. When another allied champion becomes tagged the new champion's shield is taken from all active shields equally to add to their shield.
SHIELD STRENGTH: 60 / 130 / 210 / 300 / 400 (+ 100% AP)
POWER CHORD - DIMINUENDO: Power Chord reduces its target's damage output by 20% (+2% ap) (+ 2% for each ally currently shielded) for 3 seconds.
