1. Your "prime time battle healers" is are basically bot healers (guessing other one is also)...but all healing was automatic.
Mondrian was Russian, but similar healing style.
Take away the clouds and the heal script (or even a human healer which would not perform as well) would be spread to thin and the group would have RIPed in half the time.
I did say that without the healing the fight would've been over in 5 rounds instead of prolonged 22 rounds. Since a theme of this whole thread is about whether healers have utility or not, I argue they still have great utility since the example I gave in log form shows they extended the fight, even though the battle was lost ultimately.
