Its considered normal because its flat out RNG. Some WHM are getting the drop on their first run I assure you. In fact on my second coil run both T1, and T2 drops were healing pieces. I feel your pain. In a previous game that shall not be named I ran the same raid over, and over, and over for 7 weeks before getting any healing gear. On the 7th week however no one had enough DKP to even roll against me, and picked up 4 of the 7 pieces in one run. They may want to look at a token system, but every system has a short side. The short side to RNG is that some folks just have garbage luck.
