Eh, I think that they are overrated, but still fun. Just today I played it (halo 2) for my 2nd time and got pummeled by friends, but I had fun just messing around.
You kinda have to do that when you have no choice but to get pummeled...I usually try to kill people w/ strickly nades, and then talk shit when I do...
Yeah, but they make you get so much better at using them, since you basically have to plant it directly underneathe them for a kill, or have two within a really good proximity. Fun times.
