For those of us who aren't familiar with this term, it means after fighting a boss for a certain amount of time it gets hella-buffed if you can't kill it fast enough. Armor stats go up, cooldowns go down, health regen and damage go up... basically it becomes an even bigger raging monstrosity than it was to begin with. Will we have this for all or even some bosses? I'd like to imagine that it would take out the possibility to solo play the game 100% since I cant just sit there on a ledge and fire arrows into a raid boss' eye socket from a safe distance until they finally keel over. Works for me since I prefer solo play yet, I don't hesitate to use an unbeatable (as solo) boss for an excuse to make some friends and raid together.
