The only one that needs to come back when he understand the game is you. Revenant is not going to get any more buffs, at best he will stay the same, but its very likely to go downhill.
His climbing is in the point where its needs to be. 2x higher is exactly this 2x HIGHER. You can climb many stuffs going straight for them, not trying to hang up on the other in order to get to the top. Also the slowing effect really kicks at the very end.
But you also forget the most important part, that he is climbing way faster in the beginning compare to other legends, which is a huge +, because if you are trying to get a cover fast, you will be doing that way faster. Also when chasing or being chased.
- He can also climb shorter walls 25% faster because it takes longer for his climbing speed to decelerate.
