If you're grinding for it then I'd always say yes. But if you're buying it for plat/aya then it depends on if you like playing it. (that and I don't actually know how good inaros is personally)

For not dying? Yeah, sure. But you're going to need a good ass gun.

Rework coming. Should be tad better.

Inaros is pretty tanky for a bit but really starts falling off very quickly around when you start seeing level 200 enemies, depending on the faction.

Well i would rather suggest that you get revenant prime because if you mod it correctly, trust me you are not going to die anymore , but sure if inaros is your cup of tea i respect that, the new rework should make him not so braindead

Its a frame that is very easy to make sufficiently tanky and have good sustain with, but nothing more. Incoming rework might make him more interesting

Revenant or octavia is better.
