I left WoW to come to guildwars because I was led to believe there would not be a grind. I have gone through the game and find myself wishing for the beta days when you could just unlock the skills and compete in pvp. First and foremost you should not make the pvp players suffer through the grind. If I want to make a character to tomb or gvg with I should be able to make whatever I want with whatever skills I want. I am now "stuck" with a level 20 warrior/mes to tomb with. Yes I could start a new character but to be honest I can't bring myself to get out of pre sear. I think the optimal setup would be similar to the BWE setup.
1 roleplay character is all it takes to unlock weapons, items, and runes. The pvp characters have every spell and armor set available but need the rp characters to unlock the various weapon hafts and runes. This promotes both pvp and pve but doesn't give either a advantage.

. At lvl 20, most profession quests are a few seconds of time to complete. Then you would have them all.
