where were u when UKF got a snare, usf gets a morter, no double sniper for SU and HMG got 4 Men. 
Why not the 5men when u got T4 and ur grens vet3 ?
or make them 280 and the option to get 2 LMG... or make the lmg better.
There is a quite a difference from a newish faction getting a snare and getting 25% more models just slapped onto a squad thay was designed and tweaked for the better part of a decade without.
Look at the trouble 7 man cons are causing and they dont have most of their firepower concentrated onto 1 model (which is like so to offset the low models, incase you didnt know, which im certain you didnt)
Again, usf got a mortar because garrisons were an issue. A newish faction lacking fundimental tools experimentally proved to not work as the strain on having ti tech nades was too inflexible for what was supposed to be the most flexible faction.
For the 2 man sniper, for years i had been offering solutions to the issue and was still fighting against it after launch so.....
And hmg getting 4 men? Are you talking about back in BETA? like before the game was actually released? Before the game features were firmed up and things like penatration wasnt dynamic, scatter was fixed at all ranges, shreks had aoe like tanks, the elefant was a stock unit? Back then? Id say since that was before the game was released and not many years later we could let that one slide under "faction not actually completed and still up in the air" Territory. Ost if very well established now and 5 man squad durability can be attained otherwise without screwing with faction design.
