Major lag in Frontlines after PVP update

There's some major lag happening in Frontlines PVP matches after the PVP relaunch (with the new abilities and everything). My connection status is excellent and no other areas lag -- not even alliance raids. It also doesn't happen in Crystalline Conflict, only in Frontlines and it happens in every version (Onsal Hakir, Seize, Shatter, etc.). It's particularly bad at the beginning once all characters have loaded in and the first clash happens with the enemy team. Characters are sliding all over the place. I have effects turned off if that matters (and it seems like it doesn't).

Other players report this too so it's not an issue with my ISP or local connection.
