Hurox I'm a Maeve main and your math makes me giggle, and I mean no disrespect by saying this. It's just that your math tells me that you heal yourself for 1500 every 13.3 seconds on average from 1 card (roughly, let's ignore the weight of every action), while I have pounce on a 10 seconds CD that heals me for 350 only if I hit something with it, so basically almost never.
That's what I'm talking about, low CDs and/or high heals means very little downtime.
Flanks should have downtimes linked to CDs, otherwise they become very mobile damage champions, I think we can all agree on this.
