Because SH is already capping by the time we even get to drek, then we have to clear IB tower, THEN try to take IB if it's not turtled; if horde dies on belinda, their run back has multiple path options to get back to the fight and to avoid the alliance zerg(We're usually still busy on drek/tower) whereas if an alliance dies at drek/tower without IB taken, and since SH is contested right off the fucking bat, we have to ride back from fucking STORMPIKE, and THROUGH the horde who ALWAYS gank every person who runs by, and we have ONE path choice: Up a thin hill past a horde-targeted tower past SH gy where there's even MORE horde sittin around defending it. Aka, alliance are afraid to die by pulling drek and with good reason; not to mention belinda just sheeps the nearest rogue, while drek fears the entire fucking raid all at once, which 90% of the time just "happens" to send them ALL out to the front door and out of los of drek.

Balanced my ass...grumble grumble lol

Lazy man's edit: Replace all instances of "Drek" above with "Galv"

As for Drek himself...I usually don't see people being too shy about pulling, problem is tanking him...if there's no raid-experienced tank available, I WILL pull aggro off any other tank. I have to hope the healers are paying attention and realize a boomkin is tanking since noone else can out-threat me lol
