Which is why I suggested an increased price. 70mu say for a single lmg that is designed to be used in pairs AND locking out the 7th man would be a heafy price to pay. They only have 1 slot so if the price is right it won't be an issue. Worst case an inferior version can be made to ensure its not broken. My main concern here is making the bundled call in worth it which it currently isn't, it restrict ass guards without really making the bundle worth calling in anyways.
Bundles HT do not seem to be worth it.
On the other hand Assault Guards with Thompson are actually very powerful and they their should be restriction in their numbers.
Changing the M5 to an USF M3 and lowering CP to 2 might be enough to make them attractive even without drop-able weapons (which is actually a very design imo).
