Is this a viable PvP Build? I prefer Plasma Cell over Armor-Peircing Cell personally. http://www.torhead.com/skill-calc#800ZrffRbzRkfbsZcGM.3

For those of us who have unlocked it, is it available in the collection so any of our toons can get it, or if we want it on a second toon, do we have to buy a second one?

First, does "dumb-firing" missiles work (that's firing missiles without a lock-on)? Reason I ask is there a few objectives I can't complete not matter how many locked-on missiles I fire, like the Destroyer bridge or the communication spikes), and maybe 2 or 3 more missiles would work)). Second, is there an upgrade that allows you to fire more than 4 missiles at a time? Third, is it me, or are there 2 types of shields, one that makes the target immune to blaster fire, and that isn't overloadable (destroyer-bridges come to mind) and the second type protects a little bit, but falls after about 10 seconds of powered-up blaster fire (frigate shields and some of the shield generators on Destroyers come to mind there).
