Behold now Behemoth FATE

First time seeing this FATE ever appear and I decide to go as a healer as I thought it would be a lot more needed in a FATE like this, Phase one I got gold and had no troubles but in phase two it didn't even acknowledge my presence despite keeping the tank alive through massive damage and several of our dps (I was in a full group and we tagged Behemoth in case anyone was wondering)

I'm just wondering why this happened and I find it really annoying that it screwed me over like this considering how ever other member in my group apart from the other healer got gold and the achievement, guess I won't be healing FATE's anymore if this is the trend
