2 boons in DFO regarding this, are one character per server per account- most people will not have 5 alts in DFO - and UO type skill-based system, enabling constant and unlimited respec.

If we have to many dps mages, and not enough tanks.. will probably be able to find someone bored with playing dps mage and they can just switch the skill set. Besides, open warfare often revolves around making best use of what you have, unlike PvE set scenarios which revolve more strongly around filling certain roles.

Still, its kind of a wait-and-see type of deal. I have an idea of how things could play out in several different scenarios, but seeing the actual game for the 2 weeks or so of open beta we will have... is going to have quite an impact.

I have 3 different recruiting models in mind at the moment, but will need more data on how the game will play and clan management features as well as who and how many KGB initially show up to make a call on what model we ultimately go with.
