Cloak was separated in two groups because they learned the majority of the fed players would just sit there waiting for the klingon to decloak. They wouldn't even bother using their own abilities to repair themselves, change position, or try to locate the klingon vessel etc...
Deer in Headlight syndrome -- Feds have it
edit - The K'Vort needs to be added with the same BO layout as the Excelsior - with stats that befit a cruiser not a BoP.
Im arguing against giving any ship that has lots of hull and powers for tanking that hull a battle cloak, not against klinks getting a k'vort.
