shadow protection:
-overwrites prayer of shadow prot
mind vision:
-range is only target range (should be 20k yards or something)
-disappears once target stealths!!!
-cannot be used on friendly players/npcs!!!
-rank 2 can't jump from target to target!!!
-sometimes disconnects/telports to where target was
-sometimes causes fall damage after mind visioning someone who fell down
mana burn:
-can be cast at targets with no mana (fizzles at the end of cast instead of throwing 'invalid target')
mind control:
-can be dispelled by purging the channeling priest (don't remember if it was like that in retail too tho)
-if the initial cast is interrupted, the casting bar will go on anyway infinitely until you press esc
mind flay:
-sometimes ticks only twice or even once, depending on (server) lag!!!
