Jyn is a good toon, but is a little outclassed by the current meta. And trust me, I ran my g11 double zeta Jyn for as long as I could.
She is still a great lead for TW and lightside TB, so if you're going to get her, I would do it for those reasons.
Yes she is good in raids, but if you already have CLS, you don't really need her. It depends on how long your guild takes to do HAAT and if you still need to send in multiple teams. If you don't have JTR, CLS lead, Jyn, R2, Thrawn, Pathfinder was doing 5.5 million in p3 of HAAT for me, though you could easily throw Raid Han in there.
In the team you list above, she is likely to die first, so the revive won't do you much good. In theory, a Hermit Yoda team should prevent the need for revives, so her role would be more for the stun and granting tm. With R2 and CLS, the triple stun can be fun.
For an attacker, she has low damage. About 4-6,000 on basic, 9-10,000 on Truncheon Strike.
Again, I'm glad I have her for TW and TB. But at this point in the game, I wouldn't farm her for arena, and maybe not even for raids if you have CLS.
