Remember, SE stated multiple times there would be other quest systems besides the main story and guildleves. I honestly don't think SE is going to leave us without stuff to do since that's counter productive for a MMO. It'll be interesting to see what SE decides to do when open beta starts on Monday!
I also agree with handling my MP. It was no problem at all. Besides having a decent pool to start with, you have (for conjurers) Radiance which refills MP based on the damage it inflicts, and Tranquility which gives you roughly 50% MP every 30 minutes. Full blown aetheryte crystals and smaller nodes are plentiful on the map and usually only a five minute run in between each so it's not very hard to refill your HP and MP. Just remember that you cannnot refill during leves , but I understand that's part of the challenge.
