I have a couple alts and I understand not letting them play in the same campaign if they are different factions. Before I knew, I entered 2 of my alts into campaigns to do quests and skyshards but didn't realize the impact they have when wanting to choose a different campaign for my main.
The problem is being able to switch campaigns is tough when there aren't many to choose from and the time they run from and the cost of AP. If I have a V! in a dead campaign, he can't make any AP to pay for change,
What we need is too be able to totally quit a campaign if we could please, Even if there is a week penalty for quitting, Maybe there is a better way to do this and I haven't figured it out yet?
