I log out with one round in my grenade launcher (gl). Log in......it's empty. Plus, lets say ammo drops. You walk over it get, the little loot noise goes off and you don't get the ammo.
The only time I've picked up a single piece of ammo in 2 days I pulled my GL before I walked over it and actually got the ammo. Log out for 15 mins and it's gone when I log back in.
The fact that you have 7 grenades and WT1 and above mobs just step out of the grenade radius makes getting ammo ridiculous.However, whenever they decide not to step 6" to the left, they survive the grenade anyway so you have to either run yourself out of grenades to kill them (if your lucky)or just drop em' with lead which gives NO chance at specialized ammo. Sure you can blow them up with enviromental items, IF they take cover behind them but it's random if you even get ammo. Look at Sharpshooter. Just with a assault rifle you have 800 rounds. That's 800 chances at specialized ammo... The percentage chance of getting ammo to drop (outside of SS) is a joke then there's another chance you can't even pick it up.
What's the point of specializing if it doesn't work and causes more stress than enjoyment?
