I can't comment on the glitches of the mods seen above, don't know if that is cheating or visual glitch.
The mods themselves are clearly above any know mod-caps for sure.
NS however I can say is a royal pain for Phoenix to face once they have Zombie.
Phx lacks AE's or even large DPS singles besides Ezra.
So being able to take down Zombie's Taunt long enough to also take down Daka & other NS 3x to remove extra rezing & only be down to Zombie self rez is often far to long for Phx to stay alive.
Finally, GW is going to suck royally at your level.
GW uses the old "Stat Power" v/s the new "Galactic Power" rating.
The problem..... Stat Power doesn't include the G.Power from Omega's & Zetas.
So a team w/ lots of L8 abilities will have way more GP but per SP they are the same as a team w/ the same gear but only L7 abilities.
My suggestion is start spreading some Omegas to your Phoenix Uniques if you have not already, possibly also the Basics for Ezra/Zeb. I did those & it made the climb from 76 to 85 less painful in GW.
Finally, make sure you have multiple teams, by 82 I was running Phx, Empire, Jedi, & Scoundrels & would use the weaker ones in early GW battles to pump up TM.
When I would run into a NS team like you did, I'd feed them a low L50 team of random characters to burn their big secondaries on.
THEN, I'd feed them my Empire team which would AE the NS & burn all Protection & kill off a single sister if I was lucky.
Finally, I'd go in with Phoenix who now only faced some wounded NS w/o secondaries up & my PHX had TM boosted from being used in previous fight w/ all specials ready to launch.
