I can't speak for pvp servers but I'm sure it's a nightmare.
Forced kiting? Haven't seen anything that requires it to be kited unless that's a pvp thing.
Beam was easily avoided on dps/heal characters and with tanks I hit defensive and deflection. Hardly a scratch, just the annoying stun for a few seconds.
I probably wouldn't be as thrilled if I were actually trying to farm this one. Just killed it once on every character for the update plus two extras when I lucked out logging in to a boss being up.
