It wasn't clear to me that I was starting a new party - I think the MP tutorial could use some fleshing out - so I ended up selling their gear and now they have crap because all my gold goes to my campaign party and I continually get schooled by Gary who's team has all kinds of kickass powers and spells. The only way I can see this working is to restart from scratch. Is there a way to reset/restart it all - ideally without something involving my campaign party.
There is no way to restart mp, without resetting your whole account (which is a manual request to the devs). So probably not. However, the game will be reset at least once before release - so everyone will get a restart sooner or later. Otherwise stay out of MP until you can get decent sp gear to use in MP - either way works. (Or purchase new starter packs)
