Bosses with cooldown timers - Just because something CAN happen every 45 seconds, doesn't mean it WILL.
Stupid bird-brained, hunched over, feather butted SOB. You'll rue the day that you lorded over our dead bodies with your 5% health, so you will. When we're level 80 nobody will come to see you and you'll be reduced to joining the strip poker game run by Rags and Ony to earn money, you'll see!
What do you mean, you'll win by default? Maybe they'll get clothes by then!

Funny thing is, people still do Ony. One of the BT guilds on our server has started getting MH/BT cleared by the weekend and thus doing old-school Sun / Mon raids. We did AQ40 yesterday :D Money's surprisingly good for the old-school raids; Ony drops about 120g and an 18 slot bag, plus 4-5 Epics and 2-3 Blues.
