List of classic things VZTZers have qq'd about so far:

IMO group pvp is fun at all levels and with slower exp it'll keep players in many ranges longer which is a good thing. If you make the exp too fast then noone will waste time pvping during the leveling process which will significantly detract from atmosphere. Plus I like both pvp and pve equally and I'm sure the majority of players share that sentiment so a server just for pvp would only cater to the minority.
