With the old revenge arrows you can buy time to let the arrows do the work with healers and riposters. Without those arrows to do the work, my view is that you open yourself up to just getting sniped if you don’t have anyone that can effectively do damage to the attacking team via normal strike or special. 20% heal isn’t that much.
Basically pump tiles through until you have specials charged and kill off someone. Lather, rinse, repeat until defense team is toast. A few fast mana strikers (or even average defense debuffers) and a healer and/or healer/ attack buffer will eat that team alive without the revenge arrows doing the damage.
