KDFs aren't "op". The content and ships are basically similar, with some subtle variations. The average KDF player may be a lot better than you though. Because the average fed player isn't good at games.
How about they just Make some Klingon looking ships with the same layouts the Feds have. Oh wait they wouldn't sell because you wouldn't be able to equip DC or DHC's. Lol, or maybe they should just take that off of the KDF cruisers and give some small fragile escorts that can equip them! Then the PVP might be worth doing other than on my KDF toon! Ahh, yes I have a KDF toon too! So, I sir, am not just speaking one sided here! The KDF ships are much more powerful for that very reason. So, give it a rest there young laddy! You can't convince someone that already knows better! These new ships will just put some fun back into my Fed toon.
