Unclear at present, however if you check the notes on the F2P setup nobody is going to get Klingons unlocked until level 25, or at least that appears to be the plan, so we're going to have to check out the new Klingon progression at some point.
I'd really like to see the KDF unlocked. There seem to be more than enough testers on the FED side. I'm not sure how many of the testers would go KDF, but I'd be one of them.
With the changes to the mission structure and having to aquire Dilithium, I think the KDF needs to be looked at since there is a lack of content, we need to test how this will affect KDF play.
I'm worried about is the the KDF will continue to ignored. Cryptic has promised to develop the KDF, so I'd like to start seeing feedback from the KDF side so they don't get moved to the bottom of the pile.
