No thank you... In PvP there is hardly a problem with overheating.
Maybe something that gives the pistols better Aim.
Steadfast - Pistol is modified to have a better grip, thus making the pistol easier to handle. (+25 Aim) Or something like that.
Also, make a higher and better version that is Armstech Only useble.
And the same for each crafting skill. Like there are Biochem Only usebles today.
