go ahead and play your game where you can stand in front of each other and press 1-2-3, 1-2-3, and call it "fair pvp"
If I were you I would refrain from giving advise about a game you so clearly have no idea about. WoW has more than 10 million subscriptions of which about 7 million are active. If you want success, balance and diversity of gameplay/gamestyle you should look to Blizard and their game about what gamers of all types want.
As for the PvP in WoW I guess if you played it ever you were one of the whiners that simply could not "get it" and hence whined, qqed and in the end quit "for a game with real pvp".
No I dont believe Fonline has a decent PvP system but its not the designers fault, its the actual game and the limitations it has. There is an inherent unbalance in the various "combat styles" due to range etch. Also the essence of the PvP here is "You appear next to another guy in a random encounter, whoever is more prepared to shoot at a random person wins" off course gear levels and stats matter too (a blue suit wearing combat armor and having a gun but with his 30 hp and 45% small guns will still lose to a less equipped level 15 guy).
But in the end i dont consider a sand box game a game where I should expect to be killed 100 times while going from one town to another. I expect that it will be a diverse world where I can enjoy more than one thing. PvP, PvE, questing, crafting etch.
In the bottom line Fallout was an amazing RPG... not an amazing combat simulator. You could avoid almost any combat with high enough charisma and intelligence or luck and speech. You could replay the game many times and every time have a diffrent experience.
What most players argue is that it is for this Fallout feel that they come to Fonline... if they want endless PvP and to pit their wits against fast reflexes and skilled 1337 sp3@k3rz they would go play a first person shooter with amazing up-to-date graphics.
