How to mod SLKR team for Arena?

So here is my SLKR. I finally unlocked the mastery on him. Struggling to win in Arena vs anyone. Not sure what I'm doing wrong.

Speed is low, health is low. Who are you fighting against?

SLKR mirror: you use SLKR, KRU, FOST, Sith Trooper, and Hux.

SLKR mixed (not all FO): SLKR, KRU, FOO, Sith Trooper, Hux

GL Rey: same as mixed above, or Thrawn instead of FOO

GAS: same as above

Padmé (if you still see it): same as above

If GAS is on the enemy team always stab him with your first move to take him out of the fight for two turns.

If you're doing all the above then it's either a strategy problem or a mod problem.

By unlocked his mastery I assume you mean Ultimate?

Even without an Ultimate you should be able to beat absolutely anything but another GL, and even then you can usually carefully win against Ultimate Rey.

I'm mainly fighting vs Mirror SLKR, GL Rey with GAS, Jedi Luke, JKR, etc, There are a those Jedi Master Luke Skywalker teams in the top 20 and top 10, but I hang around rank 40 or 50. Its a Dec 2015 server. I have tried SLKR, KRU, Hux, Sith Trooper, and FOST, and also subbed in FOO (taking out FOST). I also tried doing some hybrid team with SLKR, Bastilla Shan Fallen, KRU, Malak and Thrawn..which I think that one did ok vs GLR teams.

My SLKR is R7, KRU R7, Hux, ST, FOST, FOO are all R5. I am really lost on what to do. I think I'm either messing up my attacks or modding or both. I have an offense and health set on SLKR..Offense on Arrow and Cross. His Damage is 12,240.

Usually it's the support mods that are the problem. There's wide variations in how people mod SLKR but generally you want 110-120k health and at least 11,5k damage depending on what your triangle is. Hux needs to be fast as possible. KRU and FOST tanky. Either defence with health primaries on KRU, or health with health primaries. Then FOST is the same but with protection primaries. FOO is speed. ST is heavy offense. Like 10k or more.

Ok, Thank you for all the knowledge. I will work on these Mods...does Protection not matter?? I currently have:

SLKR-109k health 456 speed, 12,2k damage
KRU- 65k health, 72k prot, 231 speed (2 def sets, 1 health set)
FOST- 70k health, 110k prot, 199 speed( 1 def set, 2 health sets)
Hux- 287 speed ( 1 speed set and 1 health set)
Red Trooper- 233 speed and 6900k damage ( 1 crit damage and 1 tenacity set)
FOO- 275 speed (1 speed set, 1 potency set)

So from what you said my Red Trooper is waay low on damage...which now makes sense as I was wondering his purpose, he never kills anyone for me..dies super fast.
