I couldn't tell you.
I'm just giving you my opinion. I think the live version is incredibly strong, and thought the first revision was a fair change. I'd completely disagree with their assessment that it is weak and that the revision wasn't user friendly. Its the same as a Grenadier Rifle grenade, and would most likely have paid for itself with 3 uses. It even had the upside of not knowing when the Grenade was going to be launched.
I've been using the ability for some time and I consider it more like a long range with lower impact flamethrower vs unit in cover.
