Overall DPS is largely meaningless when it come to infantry AT weapons. Most competent players won't maintain range for more then one round to go off. Whether reload be 5 seconds or 7.
And in the case of Pschreks it's usually their high alpha damage that is so powerful.
Sure if the tank isnt snared. But expecting it to be similar to performance to a Pshrek is just never ever going to happen. I am OK with this if it got a buff in another area. Be it accuracy or Pen. Because they can be on every USF unit if you have the muni. You dont need a dedicated unit to use it. Just the muni and ANY squad at all.
