Getting sick of slayer maps

Ok, nevermind the fact that there are only 5 at the moment and too many times the same map is picked multiple times in a row. Is it just me or do the maps feel like they mostly favor camping and the use of semi-auto weapons only? Too many times ive been in a long range battle almost about to kill someone when they just edge back under cover leaving me to only be picked off by another enemy. I feel like there is too much cover and most of the combat becomes a edging war. There are too few situations in which having an assualt type weapon becomes viable. Too far away and get demolished, mid range still demolished, and good luck closing the distance on somebody without getting either picked off, double teamed, or getting killed by cqb weapons. Its not total gamebreaker for me but I really wish I could use the assault rifle and not feel outgunned the majority of the time. I don’t know maybe I’m just doing it wrong. Anyone out there feel like they can consecutively fair well using automatic weapons?
