Perfect implies flawless.
The balance at its current state is messed up.
Don't even talk about PVP until balance is sorted out.
As for MMO capability, sorry - I just don't feel the game devs have much to gain from allowing permanent world.
Best to develop content packs that adds new adventures and skills, tweak the balance, build on the foundation.
I agree with this. Allowing for persistent worlds with PVP would require a lot of re-design and re-balancing that doesn't seem to be a part of the original design concept.
That being said, allowing players to control the "AI" units in fights would be a great feature. It would be PVP-like (without all the need for rebalancing) and would allow DMs/non-persistent world creators another level of enjoyment.
