Thank for trying to derail yet another thread.
I suggest you open a dictionary and check the difference between "not that great" and "the ability must be fucking garbage". But we already aware that you use the term "garbage" rather loosely from your claim about the USF mortar.
I believe it was you who decided to dedicate several pages of the USF balance thread to cryposting about the Ostheer mortar and deliberately misreading the responses you received to perpetuate the derailing, not me. If you desire to improve your reputation on this forum it might be best to keep to facts from now on.
In any case, this ability has undeniable utility compared to the stock flame grenade and exists in a very competitive doctrine; the idea that abilities have to be overpowered in order to merit their own slot is a fantasy; USF rifle company had a slot dedicated to 45 muni flares and 15 muni sprint + debuff until this last patch, and in live game Fire Up still retains a whole slot for it's worth, albeit now without the debuff.
Not every slot has to be a home run in itself, especially not in Special Ops lol
This all said, tbh I wouldn't mind decreasing the windup time some, though I'd be lying if I said I didn't think the Molotov merits that sort of buff a bit more. (Or a cost decrease, considering the whole tech required for it.)
EDIT; I just checked and the windup/winddown for the grenade assaults are the same as normal grenades throws... The delay seems to be on the ability side, which explains some.
