If grenades are removed that makes the Rogue less balanced... grenades are one thing they can excel in.
I must politely disagree with you.
Rage + Flesh Sacrifice + Scoundrel investment + Backstabber + Dual wielding + Vault + Guerilla = 3 AP, easy 600 damage, lined up for a backstab, and it has travel that does not cause surfaces to affect you or enemies to opera you. Grenades are icing on the cake, and since anyone could use them, I wouldn't think it fair to say they're strong on rogues. I'd just say they're strong in general.
