I get rid of mines and make ammo unlimited. I hate being bogged down with mines everywhere I go. Sometimes I think, ok let me get back into a true assult with mines, but then I get bored trying to clear them all the time. I dont buy them either.
Running out of ammo is just a pain in the butt. Even though it makes it more realistic just one of my pet peevs when I do run out.
Fast arty is a must for me as I can not stand sitting there for 10 mins watching each and every round miss it's target.
If i'm going to miss what I want to hit let me miss all at once.
