Ogryn to me is the best support character.
-He can revive while taking damage
-He can countercharge the mutant and other close range special and elite enemies.
-he has enough stamina to push attack and block a lot more than everyone else making him better at clearing hordes than most of the classes.
-his health pool usually makes him not the first one downed.
Ogryn just needs his guns changed. Most ogryn guns need more ammo.
-kickback shotgun should be buffed in reload speed or damage.
-Ripper gun shouldnt be a shotgun type weapon, it should be a gun that just fires massive shells kinda like an ork weapon and it needs a slightly bigger mag or better reload.
Single shot grenade launcher should have a lot more ammo.
Grenade gauntlet is almost fine as is, probably just needs more ammo.
Heavy stubber should hit a lot harder, at least harder than the recon lasguns bc it is still less accurate than they are, and it should have a crazy amount of ammo.
