I understand that limiting PvP was done as a response to many people complaining that they were being attacked all the time, and I understand that when it comes to PvP, it is very hard to please everyone...

This being said, might I suggest another option... Instead of limiting PvP, how about giving it more player control? For instance...

Instead of clicking on someone in wilds to attack them, you could add in a "Challenge" feature, in which you challenge the other player to a duel so to speak. Make it where this player can accept the invite to battle, or deny it. Now, Some players would abuse this feature and never accept any battle invitations. So move that limit over to the amount of times that one person could decline a challenge daily. (To make it where one person couldn't just challenge someone over and over until they've reached the limit of declines, give it a cooldown timer per player for challenges)

You could have it to where the invite to battle pops up like a guild invite does, except have a timer on it (anywhere from 30 seconds to 1 minute) to where if the challenge is not denied or accepted within the time frame, the battle starts.

Furthermore, these "Challenges" should not apply to revenge, and you could also limit revenges to 10 a day as well. I think this would be a more efficient system, and give more player control over the entire PvP aspect of the game.

I understand this would mean more coding and testing, but I do believe it would be a great both ends solution that would make everyone happy given players are about half and half on the PvP limit. Would keep coiners and free players alike interested in the PvP aspect of the game.
