Needs to be nerfed. His speed boost its too powerful to be a unique ability rather than a leader ability. Droid teams being able to combine the speed boost with another leader ability is a big oversig...
I don't think JE need nurf. Old meta (OB(L),RG,Rey,GS,Jinn) is doing fine on attack vs droid team with B2+JE. When I say fine, over 90%-95% win rate. You must be really unlucky to lose. Just ignore the droids, kill B2 first, stun JE when you are close to kill B2 and then kill the remaining droids.
