dude buy mei if you want a girl merc. viper and scorpion sucks. you can only equip 1 primary weap at a time since there isnt a backpack and you cant equip it either. Also, the medkit blinds you a while like a flashnade. how i know? my friend is bought viper, medkit, etc. even she regretted buying viper and now wants to buy mei.
Yeah, if u gonna get specialist, get scorpion. Even though viper is hawt its not worth it. get the protection bonus for scorpion. I got sat which is pretty good, but now i got chams so =( but then again i can pretend i use sat not chams =). also i used m416 CQB or whatever its called. I think its pretty good, but i would prefer claymores for specialist or just not get a specialist and get a sniper =).
