Forum:Classmod and Level

I have been wondering, i play as a solider, and my 2 best Classmods are over 20 levels below my soilder, i use 2 Different Heavy Gunner mods, One is 65% mag size, i think 3 impact, and 2 metal Storm and 50% Fire Rate increase, the other is 65% mag size, 3 impact and 33% Damage increase. now my questions i have seen plenty of with a 70% mag size and three skills it increases such as impact, overload, and metal storm but nothing has come close to the 50% Fire rate, as well as the 33% damage, i mean am i missing something or it my 50,000 dollar mod out doing the over million dollar C mod, is this just a problem with the solider class, xbox GT SinsterNobody
