the Mexas C2 basicly is a upgraded L1a5 with better optics and improved ammunition and other technology features as well . the ammunition for the tier 5 leo seems a bit weak concidering how the regular tier 3 leo 1 hits , i think it would be more like a tier 6 or maybe..... a tier 7 at best . perhaps give it better ammo [ more pen and damage ] , slight increase in vision range , better acceleration concidering its lighter armour component. I still would like to see it in the game . As one of the last greatest versions of the leo 1 class.
