2.55 Main Scenario Requirement.

[morruin]

As a recent returnee I think the 6-10 hours mentioned is this thread is rather optimistic.

I have just taken 6 days (not full time obviously) just to clear The Chrysalis - and I benefitted from being a healer and having other (higher iLvL) people in the DF roulette.

A fresh 50/returnee player need to follow the MSQ - and gear up himself by running other content. A dps doing the MSQ after the expansion has launched will have a lot of queue time and less players in the DF (they'll be off flying around Ishgard)

I liked the solution from LoTRO. The MSQ there was split into chapters and you could start a new chapter (tied to expansions in the beginning) without having finished the last one. So your questlog could read something like
Chapter 1.12.5
Chapter 2.9.6
Chapter 3.6.8
and you could go back and finish them when you wanted, without having your progress blocked.
