I just hit 70 on my priest, and as a reward I'm going back and clearing all the old raids I never got a chance to play. I jumped into Primeval Feast and after some learning I figured out how to clear some of the mobs.
The problem I'm running into is that the switches for Spring and Autumn require keys, and I can't find those keys everywhere. I killed the two mobs in front of the switches, but no keys or chests dropped. Any idea on how to progress?
