yeah i want non-nefed to but you know...'balance'...
your suggestion is theoricaly good, the only big dference iis the AP cost but for a critical shot you need 6AP, 5with BRoF, like a big pistol. the standar plasma rifle is able to shot 2 times too, only with 10AG and 2xAction boy, and deal more damage.
unless you change the AB perks to More Crticals, but you will only have 75% as max of criticals to the eyes, and 50% of double critical, and the standar will have 60%, with 44% of double critical. Also you need to take Better criticals, and Lifegiver.
Looks like a nice deal, but it will be like a new powerful pistol, exept for the ST requirement, most pistoleros use 4 or 5 ST, so take Weapon Handling will make you unable to take 3More Criticals, and since the range is very low you need at least 1 Lifegiver and 8END, also you need 200% or even more skill because the Plasma rifle dont have any perk (like the Laser Rifle), then youll need 6INT, but it wont be enough to boost more than 2 skills, EW and FA, so 7ST for can handle the weapon or a insanelly skill for contrarrest that is impossible. And the normal Plasma Rifle will win
Keep in count that for fight BG you need Toughness, and the Turbo Plasma Rifle build can handle 2 of them.
About the YK, nah it is useless, less power than the standar Plasma Rifle, less range and more AP, and Tesla will make the things really harsh, also all the CA have the same defense against electrical damage than plasma, and all the 1tier armors have 30% resistance, BUT it can be a nice side arm against the MA, so i will suggest to include the Pulse Pistol, (with same stats than the Laser Pistol, but 20-30dmg) not the Rifle.
