Custom class 2= Mk.60 LMG reflex sight, majestic and frag grenade. i use the same exact modules as my first class.
Custom class 3= Feline extended mags and surpressor. Frag and AY69 machine pistol. i use energy transfer 2, blind spot, and aim enhance 3/ mobility enhance.
I do pretty good with all of these but my best class is with the scar below.
SCAR class= scar ironsight, extended mags and urban camo. Aim enhance 3/ rapid fire, stealth enhance 2/ and nano recharge 2. Hammer and frag. I BEAST WITH THIS CLASS. I try not to use it and trust me i dont use it very often anymore because I want to experiment with other weapons and modules and to me, this is just too easy to use. everytime i use it i make MVP and I lovee itttt but i just get bored of it sometimes so thats why i have the class with the scarab I pretty much use all the time. I am begining to now beast with the scarab as well. Soooo what classes do you guys do good with? btw if i think its noobish imma reply to your post as noobish but dont flame its just my opinion.
