Fair enough! 
Would it really be too strong in PvE at 250 TU though? It doesn’t scale damage like bloodthirst, so I can’t imagine it’s useful in the highly buffed events.
When you compare it to moves where the requirements are so weak it’s easy to pull off the move, 250 TU still seems like a tough requirement. Thinking compared to the likes of
confidence strike,
fast strike,
slayerbane,
retribution.
Similar damage, Survivor has recoil damage too though and seems a far more difficult requirement.
I would still argue it would be nice to keep it relevant at 250 TU. Keep diversity alive!
