Would you consider adding an AP ratio to Ashe's W?
A bit of context: I've played support Ashe since 2013. Back when Ashe's passive was Focus, it made for a really strong laning phase with high powered instances of poke. She's always been a great Black Cleaver support champion and it's incredibly fun to play.
Why an AP ratio though? Ever since they added Stoneborn Pact to the game (Font of Life in runes reforged) additional strategies opened up for support Ashe because of Frost Shot, particularly using Ardent Censer on autoattack based comps (everything Ashe does triggers Font of Life, allies heal from it and gain the buff). The problem is the item itself feels fantastic to buy, but the path feels miserable. AP does nothing for Ashe except for adding 1/0.5 AP to her ult, so spending money on a Wisp is a low point.
Support Ashe can also build a couple of AP items viably, like Twin Shadows and Liandry's, but again, the AP only really affects your R casts and your ratios from runes. An AP ratio on W would have minimal effect on ADC Ashe's balance (it would increase her W damage on Baron take only) but it would be godsent for those of us who play Support Ashe, which is incredibly fun and deceptively powerful.
