btw, i was able to 5-man every instance that i entered pre-wotlk with 5 boomkin. you'd be surprised how fast you can kill a boss with 15x trees, 5x starfall, 5x insect swarm, 5x moonfire, and wrath spam. i even 5-boomkin'ed magister's terrace (regular) at 71 with crappy northrend greens-- i had about 6-7k hp and 7k mana at the time iirc
