I always prefered urban/CQB maps and while I do enjoy other maps in PR, your enjoyment of the game heavily depends on your squad. Now since I'm not part of any clan/community I usually just join random squad.
You have some days when you play for 3-4 hours and you just can't get into stride with a squad, everyone just running around like headless chickens or only part of the squad does what it's suppose to and so on. In large maps that usually just means running around for 20 minutes with nothing happening (don't get me started on all those people one manning armour or landrovers only to then go on some solo mission and dump it while people who need it then have to walk for a mile to their objective).
I should probably try and join some sort of PR clan, but a lot of them seem rather hardcore and not being at school or college anymore, it's difficult to commit on regular basis. My computer problems and BT connection doesn't help.
