Dovabear in in a class of legendary pets released as event tier rewards over the last year. These pets have similar happiness bonus stats making them stronger than previous legendary pets. (specifically they are Dovabear, Blinky, Yowie, Nilbog). Blinky and Nilbog are popular for their aa and a level 40 Yowie has great "casts ice block" on passive attack. However Dova's aa has been generally regarded as useless.

Why not increase Dova's chance to terrify (extremely low) to a level at say Clyde's chance to panic, which while less than Slag's, still happens often enough and can work on bosses. That's my suggestion.
