Just give usf easy 8's and up the pen by 10-20,nerf the Jackson to fire slowly but always use hvap, and take away the Scott's autofire but buffs its barrage.
Here is the idea:
Easy 8 added to stock lineup
Easy 8 unlocked after major and additional tech
Easy 8's pen increased by ten-20, more pen awarded at vet 2
Jackson rate of fire nerfed by a second or two.
Jacksons hvap nerfed to 160 dmg but set as passive
Scott's autofire nerfed
Scott barrage buffed and scott is given a bunker busting barrage to easily remove bunkers or destroy Buildable packs.
