PvP has no place in a Dungeons and Dragons MMO. DnD is about cooperation and teamwork to accomplish goals, not 1-upmanship to increase someone's epeen. It did not have it at start (one of the big draws that brought me to this game in the first place) and should not have been added later. It never has fit well ingame in its current implementation except as a test bed for new abilities. So here are my suggestions (in order of my preference)
1) Completely remove PVP in all forms and recode the training dummy to be able to be completely customized (hp, saves, fortification, AC, whatever) and have all abilities usable on it with extended combat feedback if wanted.
2) Leave PvP as-is, in its current form, with no further amount of developer time ever spent on it at all. Money and time already spent is gone (wasted IMO) and no reason throwing good money after bad.
3) This is my least favorite option, but lets the PvPers put their money where their mouth is. Make all aspects of PvP store-only: brawls, challenges, whatever. Any and all development costs (Dev salaries, whatever) for PvP can only go up to an amount that is capped by whatever money is brought in by PvP sales.
I am tired of seeing thread after thread about PvP when it has no place in a DnD MMO. Please remove it completely.
