That's why earlier, a pvp only nuke, with a weapon requirement (dual pistols), as what they did with doc's pvp dot, seems to be the best solution for the problem considered in the OP.
Crat want AS in pvp, I guess, to have a regular reliable source of damage. This is, as long as no serious AS pistol is released, not compatible with a pistol setup.
Now, if you'd have to define AS, caracteristics would be :
-11s lookout (can be achieved through a 11s lock out debuff or a 11s recharge)
-no counters (very low NR check, 0 to 10% NR I guess vs 100% MC... or MC 50% pistol 50% ?)
-variable damage, according to the multiplier you rolled. (random rolls, could be tweaked, base damage with 5 different multipliers)
If there are no AS pistols to be released, having a nano reproducing AS caracteristics, usable only with pistols, and only usable in pvp (as AS isnt used most of the time in pvm anyway), would allow crats to keep a pvm weapon setup (pistols) whithout sacrificing pvp capability (thx for having an AS equivalent). Ofc, due to the advantage of more procs with a dual weapon setup, said nano would be tweaked to be a little less effective than AS... what I proposed is just rough numbers (and pvm damage) that are to be tweaked for I dont know what exact kind of damage a crat would deal with an AS weapon. I leave exact numbers to people that can talk about that, just thinking of a concept.
Just some food for thoughts.
Edit. Could even go a lil further in the concept and imagine a nano with 100% pistol AR and pistol req. NSD wouldnt block 'AS'. heh
