I won't scream overnerf yet. Many of us Raptor and BoP pilots especially will have to start better managing our power and not just spam the spacebar like before. Also, with many Fed ships sporting cannons now, we have to get used to the DPS tables turned against us.
However, my win-loss ratio playing Klingon post-patch seems 50-50, which is always a good thing. I'll give it more time.
Thank you for the great replies. I must admit, I clicked on this post with dread this morning, expecting nothing but 'L2P' flames from all sides.
The comment about Fed hardcore PVPers sticking around for FvK especially made sense to me from what I was seeing. There were some great Fed teams doing everything right.
Another thing I didn't consider: On the Klingon side, we haven't had a good mix of BOPs, raptors and cruisers in the FvK I've been fighting. Depending on the effect of the patch on the various ship classes, it could be a better mix of ships on our side would resolve what I was experiencing.
