I think at my level this is the thing that is bugging me, I said the wrong grenade in my original post - this thing
http://www.stat.coh2.hu/weapon.php?filename=panzer_grenadier_bundled_stielgranate_mp. The amount of fully vetted up squads I lose to a single bloody gammon bomb grenade, which for it's potency and consistency at wiping entire full health squads seems to have a ridiculously short fuse. That is more what bugs me, and I guess it is just my skill level. But I have honest to zombie space jesus hit retreat more than a few times the very instant the timer starts and still lost an entire squad, it was worse before the patch with the bunching stuff, but I have still had it since. My issue is with the timer more than anything, I just can't react fast enough even when I am looking at the freaking engagement, I'm using hotkeys, literally see it thrown hit R and lose a whole squad.
So my issue is less with the randomness of the american grenades, but how craptacular they are in comparison.
Only the gammon bomb isn´t random, it wipes every time lol.
