Yeah I don't think any of the warbond weapons are OP (actually, the breaker incendiary is prob very op now that they fixed the DoT). And they typically balance them and fix them later after a poor patch. From what it sounds like the devs say it's not working as intended so everyone has to chill with the "THEY KILLED MY BABY!" overreaction.

There's also been some additional feedback from the balance team over the Eruptor.

Basically they still consider it "viable" after the nerf, and while they're looking at breakpoint impacts, they've said they're not specifically considering buffs. The reasons given were that the shrapnel effect was increasing damage well beyond intended levels on top of not being used the way they intended.

So basically the purported reason of removing shrapnel to reduce team killing effects was just an excuse and they absolutely intended a direct nerf. It's not coming back to how good it was before.
