Haven't used it yet, still no throw animation like other nades?
technically it does have a throwing animation, but it's very short. If I'm reading the stats, right, the throwing animation is only .25 seconds.
Note that there are other grenade with a .25 seconds throw time, but those grenade are usually used by elite troops with a 1.25 seconds fuse. If I recall correctly, the other "quick" grenades in the game are shocktroopers, guards, panzergrenadier, Fallshirm, ober, and commandos.
Shocktrooper have the fastest explosive grenade in the entire game, in terms of throw time and fuse time. IIRC it's .25 second throw time with a .75 second fuse. Most people seems to be not aware of it since Shocktrooper do well enough with their ppsh.
I think the incendiary grenade would have been better on the sturm. Right now the grenade is still instantaneous at close range. Giving it to the sturm wouldn't have change the balance too much since the sturm are already good at close range.
