SWAT is more fun with the BR's Three Shot style, its easier to get kills and it is how the game was originally played.
Don't like SWAT myself, but my roomate in the navy ONLY played SWAT in Halo 2, so it was either that or nothing and take a guess how I did with SWAT being my first online playing, and being the only halo type I played online for about 6 months.
Yeah....just like your thinking....
The DMR requires more skill and I prefer it to the BR cause the DNR ruins the point of head shots, headshots are good because they only take one bullet, plus it kills alot quicker.
But a 3 shot precision weapon is a waste of bullets and cheapens marksmanship in Halo.
Haven't played SWAT in 5 years gonna try it again with the DMR before I can't to see if I like it better, plux I have gotten ALOT better. Just take a look at my BPR and try to imagine how bad I USED to be, good luck on that.
