this is to go with my last post about teir raiding. these instances are one thats i currently know are scripted:
Karazhan: all bosses, most mobs
Tempest keep: The mechanar: most mobs and bosses
The botanica: same as mechanar
The Arcatraz: Same as mechanar
The eye: hardcore scripts. mobs act like fire mages in first encounters.
Hyjal: Rage: Frost bolt/ frost nove
Kaz'rogal: 3k slash, thunderclap, Chain Insta-wipe spell (starts 8k, stacks 500 everychain within 20 yards)
Anthereon: lol, wipe. shadow blasts, target deaths, marked deaths, chains, stuns, AoE.
BT: Naj: AoE poison wave, slash like kaz, AoE stun
Teron: Flight, beams, burning, DoT's.
thats all the ones i know of atm, lets go just run instances and die to see what they all do
(more to come as i explore all the lower instances)
