The 2-piece bonus from equipping Gladiator’s Medallion and Gladiator’s Emblem now grants an additional 5% stamina in PvP combat.
Developers’ note: This is intended to slightly increase the time it takes to kill an enemy in PvP combat, to give players more time to react to incoming burst.
They’re increasing stamina bonus because people die too fast. In BGs it’s basically impossible to heal if people know how to press buttons, because you don’t have time to react.
