I've been playing it for a few days now and I gotta say... unless people start from the beginning with it before some of our 'hardcore' members get to playing... it's gonna get bad.
Just from my perspective with my current status on an rpg server, I just run around with a shotgun and mow down almost anyone without having to worry about dying cause well, I have 300hp and I regen and leech life on top of that.
New people coming to server will hate it... the people who have been playing it for a while will love to slaughter.
On a side note, it stops people going crazy with the AWP. You'll end up having an assload of p90s and Paras
If we do end up running the rpg server occasionally, you'll have to make sure that the stats reset along with it.
