The otehr ships are not important to me lol. However tehre are a few points i woul like to make on the spider... 1.As it is an ambush ship...it really would make sence to make it regain energy with stealth and cloak on 2.As it is said "weak when exposed" it would make sence to limit it's exposure by giving it energy regaining when stealth and cloak are on. (ok it is the same point with 2 different reasons...)
