you just said a Roe tank had more HP at a lower iLvl, so you'd get that additional HP, you'd get everything their base stats offer, not just the "mechanics" it wouldn't be just aesthetic you'd be playing a Roe, Stats and all, that just happened to look like a Mi'qote. so any Mi'qote tank that was still "just" a Mi'qote would be considered "gimp" as their HP would be lower than yours.
