Hi there folks,
Relics procs of the same type shouldn't stack, and we have this bug fixed for Game Update 2.1.1. Because the fix is still in testing, there's always the chance that it will be moved to a different patch. If so, I'll be sure to let you know!
Again, incompetent developers and designers. You're creating a bandaid fix for a broken mechanic that needs a redesign. The whole RNG factor of PvP blew up in your face before, and you're regressing only to have it blow up in your face again.
