The real problem is low population on the KDF side simple as that. Instead of breaking out the love beads why not maybe do a few things to encourage people to play on their KDF? In fact if even a few of you who started KDF and then went Fed would come back we probably would be in much better shape. It's amazing how often I'm waiting in the que because we are 1-2 KDF short of launching an arena. Again, I listed easy fixes to help encourage KDF play but Craptic sucks.
Making PvP give much more experience while leveling would go a loooong way to fixing that. It's a pain in the butt leveling a KDF toon because not only do you have to PvE, but you have to do the most boring and repetitive type of PvE.
I've got 2 KDF toons stuck around tier 3, but there's no way to level them up.
