Oh, I realize that, dudemanjac, and I also realize science vessels will be fairly good at detecting them, too. However, they're still advantages in that situation, if only because the Federation has to spend resources to deal with cloaks if they engage in pvp content. To have a balanced game, there should be something that Klingons have to deal with (spending their own resources, to do it well), if they're to overcome the Federation -- be it some natural advantage to shields, or repair rates, engine power, science capability (even on non-science ships), etc. etc. etc.

I'm just curious to know if there's anything special that the federation is innately good at, or unique, which will balance Federation vessels against Klingons in PvP.
