Personally I still think Ripper is meh, but better now w/ reworked Blaze Away, though limited by massive recoil and still-low ammo. But then there are 2 big buffing bugs right now…
Rumbler is the grenade launcher game in this game (Thumper is the m79 Vietnam-era nickname for it), best of all apparently the Rending is actually Brittle!
The Grenade Gauntlet is top-tier too, the 2 fill slightly different roles.
Kickback seems a lot more usable now, better than Ripper, just don’t ADS w/ Blaze Away. Its immense stopping/knockdown power even if a weak pellet hits at range makes it useful.
