I thought this cost much more. These grenades will instantly kill garrisons and setup teams. I mean, molotov is what, 25 munis? Even 20 is too cheap.
That is an insane exaggeration and I'm not even interested in the "no it's not" retort. If you really think they clear out garrisons that easily, please post replays.
I've played with both doctrines that use Infiltration Tactics, these grenades aren't really something that I've ever thought were that great.
If you're lucky, or you know your opponent isn't paying attention, yes, you may have a big pay out, but even on an unsuspecting squad, I rarely see them squad wipe, no more than any other grenade. As it has been pointed out, the animation is incredibly obvious and the range is much shorter than standard grenades. You're also not factoring in the cooldown, unless you have a mass amount of volks, you're not going to have this ability on demand.
Infact, the only upside I have to these is that they are cheap, if it wasn't for their price point, I'd never use them over the standard model.
If they do get changed, this is going to end up poorly. If they become more expensive, they are going to be buffed in range or cast time to accommodate, or else the doctrinal ability with be without any merits.
Even if their price is increased without a buff, the ability will become obsolete and then it will get buffed to be desirable.
It's just not a good enough ability to justify anything higher than what it is without increasing something about it.
