Default Ammo Type [As a selection]

It takes away too much versatility from every class (yes even gunners use standard ammo) for me to consider this a viable option to do anything positive.

Changing the buff hammer so it gives guns more hp rather than damage would be the best thing to do. That or give gunners more tools so they can out damage a engineer with the same ammo type. The fact that engineers can out damage gunners seems like a big balance issue.
