I would rather they give JKG a 10% boost in offence, speed, and potency in her basic stats to at least make her less useless. She is a Jedi, not a generic trooper/scout.
Honestly, if a Toon is L85, 7* and G8, even without max'ed out Mods, they shouldn't be useless.
For the record, my JKG is only L50, 4*, G5, 3/3/3, no Mods. Absolutely doing nothing but be GW fodder.
The bad part is that GW and Bronzium cards keep giving me her shards.
