This thread may be locked, but i get it out of its grave because i have to say something.
p0int, as annoying as you are, you got a point (heh).
The whole "hop onto a different account because its free" thing really has flaws, like cheating, Friendly fire (grief lock? Screw that, New account!), spying etc.
While some of those may be lighter flaws that dont matter much (spying may be one of them, its easy to deal with and not very effective in an FPS anyway), cheating and trolling via friendly fire are quite some big issues that need to be adressed.
BUT, that doesnt have to mean that the game needs a box price. As seen in various games, box prices dont stop cheaters, it just lowers their population. Look at COD or BF3 and you see what i mean.
But we dont want a low cheater populaiton, we want no cheaters at all. And as it seems, the devs are working quite hard to archive that. And if they do what i think they do (and the reason why they went for punkbuster on top of their own AC stuff thats hidden within the client), then they can also do with the trolls by simply denying their ability to easily create another account (or even just switch between existing accounts).
In any way, dont blame it on F2P, thats not the problem. F2P takes away the entry barrier, and thats what caused PS to not be as succesful as it could be.
At the very end, we have to wait till beta, see ourself, and figure out how to fix the problem. And dont get into page long arguments that derail into a flamewar and personal attacks, because those help nobody.
