Nah FvK is rather easy for my Klink, but that's mostly because you hardly see any experienced Feds in FvK. Most of the recognisably good Fed PvPers stick to FvF.

Never queue for KvK, mostly due to how KvK used to be back when all ships cloaked, but also the prospect of having to face P2W consoles and drones. In FvK the AMS console is really really annoying, but it's no where near as deadly as energy syphons, tachyon drones, theta-radiation, aceton assimilators, bio-neural trics and graviton pulse.
