Yeah, that bug is... interesting. Certain spec patterns glitch the game and grant MASSIVE amounts of stats/HP. Most warzones are just snipers now. Snipers with 800k HP and about 40k dps *shrug*
Hell, I accidentally killed someone on my sentinel with a 48k force leap before I realized what was happening.
Just got 100k guard from one taunt on one of those snipers (he was fighting with another 800k sniper -.-).
My Shadow also gets 40k HP and does a little bit to much damage (10-20% I think), but those guys with 100k+ HP just ruin the games.
