One thing they REALLY need to add is a better explanation of the boss fights. I've just spent an hour trying to take down Supergirl, when it actually meant that I was to distract her - by setting people alight - then smash the consoles - which don't take their hits properly - and then find the bucket with the hidden kryptonite in it - and spam damage on her without using any of the knockback powers.
But you can't change between power regen and health regen easily, you can't repair damage and you can't get more health/power regen without taking a trip through hostile territory and restarting the mission.
This level of game meddling ruined LotRo for me, I hope it's fixed before launch.
That being said, the new patch is really really quite nice.
