Feral idols these days, especially tanking ones suck.
Below are the main tanking idols that are tank oriented.
Idol of Perspicacious Attacks - I feel this is the generic best unless for a pure single target fight.
Idol of Terror - Just glad semi-geared 80s can solo or 2 man H SP for badges.
Idol of the Wastes - Good for swipe spam or any rotation that uses swipe. It procs a lot in my experience.
Idol of the Plainstalker - A toned down version of the level 70 epic idol and if an 80 can easily get 20 badges why would anyone use this?
Am I missing any? I mean the AP ones are meh for tanking and mostly have PvP requirements. Any one hear about them giving us a few decent options for this slot?
