Yeah it's a lot slower pace than DoD, since most people are sneaking around and taking careful shots... running in rambo style like so many people do in DoD simply isn't an option when getting hit by anything usually means you're either dead, disarmed, or injured so badly that you can't run away... and you never know who shot you.
Like BIOHZRD03 said above, DoD is definitely where my heart remains, but RnL is a really good alternative to it.
