Incase if people wonder about the support trait from Salvation Traitline:
Dodge rolling removes a condition from nearby allies
Has a 10s CD.
By comparing this to the trait Warrior has on dodge (nice damage on dodge) and Thief on dodge (Vault or Lotus) which are all strong dodge traits, and also the Guardian heal on dodge. Those all have no Cooldowns.
Why does Revenant have a 10 second cooldown here? In PvE it wouldnt be OP anyway, and in PvP/WvW it would definetly help against the condi meta, the removal of the CD would be fair
