Minis are a great way to gain pvp experience, and no im not talking about xp, i mean real experience. Your on a PVP server, you need to learn to pvp, if for nothing else just so you can defend yourself while questing.
But more than anything its fun!Take a break from turning in your quests and do a mini. enjoy all aspects of the game. who knows you may even like it and start looking for it in open world.....then again i'll be out there too
