We've had this discussion more times than an elf with supreme INT can count.
From what I can remember of past discussions everyone have their own idea on how to change PVP. Meanwhile upstairs, there really has been a lack of available wizards who could potentially change it. I've always wanted to, but I don't have the authority nor the knowledge to do it. The same goes for the majority of wizards. Lately, as you know there has been more activity in the wizard world, just like in the game as a whole, so maybe there is a chance something could change. If someone can decide _how_ to change it. However, it also feels like a lot of players do not want to be part of PVP at all, and just want to mind their own business, and maybe are quite happy with PVP as it is. That is, not a very big part of the game?
I think of you players (wizards included) _truly_ want PVP to change, I would recommend creating some sort of group (a thread here, or group on discord maybe?) for it, come up with a really good idea, and send it in to the admin, signed with a large number of player names. Posting random ideas here makes a fun discussion (again) but for an actual change to happen, a much more serious idea has to be presented, and with a lot of backing. That would also a relatively united playerbase asking for a change. Who wants to take charge?
