I suggest moving Shyvana's AP on-hit ratio to Flame Breath instead of Burnout

Currently, in Patch 6.10, Shyvana's Burnout (W) has an AP ratio on the ambient damage from the ability and BOTH AP and AD ratios for her on-hit bonus damage during the ability.

I think the mark from Shyvana's Flame Breath is more appropriate for an AP ratio. This game gives more reward for landing Flame Breath (E), which feels pretty binary and uninteresting without some sort of ratio. I'm also concerned that having both ratios on Burnout will narrow her strength onto that ability alone. Even if you don't put an AP ratio on Flame Breath, have the base %Health damage increase with rank.
