Stacking Class "Special" Buffs : Star Wars Galaxies Nerfed Info

Items you receive at level 82, 86, or 90 (sorry havent leveled for a while and forgot) in the different classes keep working even when you switch from that class. Heavy Weapons Cooling module for Commandoor Plan Alpha for spy. These can be used througout a fight so their cooldown becomes a thing of the past, the more you respec the more you get. This is handy for soloing places because of the little extra buff, or pvp if no noe notices (this one guy yelled at me in tells on how to do it one time another time a guy started worshiping me so be careful). Yeah this is handy.
Nerve Racking waiting to see if anyone confirms this

Yay on this one. Done it for along time.

So these items dont share a common cooldown timer? Do they stack with the more common buffs like the Injector or miners medalion?

1 yay. 2 more for confirm
0 nay. 3 more for lock.
