I've been reading these forums a lot lately, mainly to gather other peoples insight into talent builds and one thing i've noticed in most builds is that many of them are marked with grim/destructive reach as mandatory spells. I have to admit that after TBC was released I became a lot more inactive then i had been before so i haven't really gotten to know the lvl 70 PvE endgame at all. Personally i would like to spend those 4 extra points somewhere else, but what i wanted to know are 1) Are these spells really mandatory and 2) If so, why? Are there some encounters where you need to stay further away from the boss/mob then you could do without grim/destructive reach?
Hope to see some replies
