I had no problem buying my spells 50-64 because prices were reasonable, and I would just wait until I could find a bargain or go farm for it with some friends.
However, I really haven't done much raiding and I am not Elemental planes flag so I only had the option of buying my level 65 spells which on my server were exorbitantly high even compared to other classes. It's like canni envy or something that someone gets a shaman spell and says let's make them actually pay for this! Fo7 is still 30k, and I sitll don't have it.
I am 66 right now and trying my best to get into WoS and MPG groups, but I still have never seen any of them drop. So should I just go ahead and buy the 66-68 runes? They are going for about 10k.
