PvP Game mode Suggestion

Another idea of game mode about giving fun to every single class and disciples comes to my mind as I talked with my LS mates about PvP content..

This time, is about a contest held from each cities which allow PvP games for all classes we can play now:

DoW/DoM
Solo and Teamed fight..
Maybe there should be a version where the equipment being used are assigned by the contest, for balancing issue.

And of course, there're always more game modes for this type of game as in many other MMOs.. Like capture the flag, King of the Hill.. Or simply have aggro mobs or boss monster fighting along side the participants.

DoH
Crafters assigned to the game will be asked to complete a certain product in a time limit.

Score will be given according to time needed to finish, and the quality of the product
(Though I don't know how the quality/HQ system will go, but there'll certainly be some way to design a scoring system which makes the players have to do their task quick and neatly)

DoL
Took me a while to come to a point how DoLs can do a PvP game with excitement.
Here it goes:

The DoLs will have to harvest a specific item as in leves,
however, items gained in the game will include buff and debuff ones which can be used on the player himself, or his opponents.

Let's say, a fish which will increase ones' speed during the game, a explosive rock which will decrease the opponent's objective count by one.. and so on.

Well there are issues like how are the different classes will be assigned to the contest, and way many other balancing issue.. but it's probably too early to think of those.. :P

So I'll stop here, what do you think?
As a player or even as the developer of the game? (if this time the thread has better response :( )
