I've been playing it a lot since I bought it a few weeks ago. I'm at level 35 (Major) and I've only run into one server that had a "no-running except under fire" rule, though I have seen maybe a couple that request that you don't bunny-hop. I gather it's to make things feel a little more realistic. I actually ended up playing quite a while on the one I ran across. Of course there are hundreds of other busy servers that all ping around the 20's for me, so I can always choose to just play TDM, HQ, or S&D.
Kantham, you make it seem as though the P90 is the only good gun in the game. I've found several that are pretty potent, especially with the right attachment.
You may not like it, but I think you're definitely in the minority. I find it to be refreshing and addictive.
