We have implemented a hotfix so that Replenishment in arenas will only affect the character and not the whole team. This change only affects the spell while inside an arena instance.

We feel Replenishment is balanced for larger groups, but just makes too much of a difference on smaller arena teams. Making the rules work differently in PvP and PvE isn’t a solution we like to use often, but in this case we think it fixes the issue cleanly, while still making the talents in question useful to the character who takes them. Alternatives, such as nerfing the amount returned by Replenishment in arena or making it not function at all, seem like more punitive choices from which we want to stay away.
