The ability to re-run Solo Duty points is a Must Have. At least the MSQ ones should be able to be replayed. Ie create a instance point that is triggered during the Unending Journey on that quest, [Do you want to re-battle? {Yes} {No}] If yes, it tosses you back in; if no it resumes the cs from the next point per normal. Would it be complicated to implement, Probably. Worth it for the player base? Likely. I'd pay to be able to rerun the Grand Melee or The Conference in Ala Mhigo to name two of the really fun solo battles.
