I think it's because Payday 1 maps often had areas where they forced you to push forward. In Payday 2 there's a lot of sitting in one area twiddling your thumbs waiting for something to finish, and then only pushing when escape has arrived. Even then you can wait for the lull between assault waves and pretty much walk to the escape.

Honestly though. A lot of the new payday 2 players suck. They get ammo even when they have only wasted a clip or two and still have plenty of ammo left. A waste. I have seen level 40+ people doing that. Health? Same thing. Half of health down? OMG HEALTH! Get downed once or twice for me then I get med bag. Of course by then it would have already gone to waste by scrubs.
It isn't a waste when a guy resupplies while he's almost full on ammo. Ammo and doctor bags use percentage based pool which is I believe 400% of 1 weapons ammo/full health and not the number of charges system.
The ammo works this way, definitely. You take a percentage of how much you're missing. Not sure about med bags, though. In the first one, they actually had a set number of heals. They might have changed that for Payday 2, though.
Oh yes payday1 missions were defe more difficult...... only by the fact that the cops had a 100% accuracy rate.
It makes snipers actually better. PAyday 2's snipers suck. SERIOUSLY aren't they suppose to be trained?
Sniper locks onto you and he is struggling to get a 'perfect' lock on you. I recall once just standing there shooting other cops and i had a sniper aimed at me. He would fire and he would miss, eventually I juust killed him. Plus the fact that some animations on the cops in the second game make them invisible for a short time really ruins it. You wastee ammo because of it.
