In Live I do remember a few JE's with over 70k on their lvl 8 shields, have absolutely no clue anymore which shields those were.
J qu ara... you have lvl 9 reactor, access to 6 lvl 9 devices, near instant warp. Cycle combat cloak with plasma beams, debuff from devices and repeat as necessary. The JE isn't designed to be a tank or warrior class, yet despite that, with some skill you can pull off some amazing things. Just work at it, it'll come along.
I don't recall enough from Live to give really specific advise (and still too low lvl now to know the equipment in the emu) but I do remember as a maxed JE during Live, yes combat could get tricky, and dicey, and suicidal. You are better as a support role in a group (reactor regen, max scan, max navigate, and all those fantastic activateable devices)
The best advise i could offer is to run 2 accts simultaneously, one your JE and the other a PW. I used to farm Cooper with my dual setup during live and it worked great (until I got cocky anyways lol)
If you can't dual or if the JE is too much for you (hey its not for everyone, personally I am horrible as a TE), then really you're better off rolling a warrior or trades class for the extra weapons to kill faster.
Good Luck!
