The team posted a developer blog to briefly discuss the upcoming patch. The biggest change is the addition of a Tenacity stat to PvP equipment. This stat will increase resistance to crowd control spells, stuns, critical hits, and (of course) damage. Cryptic sees Tenacity as being essential to those who want to mount a strong defense in PvP.
Neverwinter will also be tweaking the prone effect so that it will be shorter and affected by control resist. The team also teased new PvP gear, although it said that details about the gear will have to wait for another day.
