My comments:

Levelling speed: Using the round-based battling high level monsters are actually possible to add - with the old real-time fighting it is not easy to do balanced monsters, because they either have too strong attacks, or they are moving faster and people would complain about lag.
Higher level monsters or groups of monsters would need some intelligence and combination of attacks to beat, but would also give more experience, so it would be less repetitive.

Parties: The experience for killing monsters should not be distributed equally to the party members, it should more depend on the levels of the players themself and eventually on how much they have helped for killing the monster. If you are fighting against a group of monsters then the lower level players should attack the lower level monsters and the higher level players attack the more strong enemies. The monsters also need to attack the more high level players so that you cannot use friends for getting monsters wasting their attacks.

Enemy graphics: It would be possible to add more monsters then because we need less graphics (mainly from one side) and don't need to script complicated intelligent movement or attacks for them.

Flying enemies: would be good for the round-based battling, but it would also be good to have some lower level flying monsters to make the overworld more interesting (killer bees on the grass fields, bats in the mining caves).

Pets: Could get stats like the players and be used a side kick for the round-based battling. It could also be interesting to use them to make the jobs less repetitive - e.g. using a pet for mining, and after some time you come back and get the iron and gold. That would require a limit though on how many pets you have, but if there is a limit on the number of pets we could also add some call-pet spell or such things.
