Ok so here is a few things I have noticed and thought could improve the game :)

1) When you reach the higher levels (say 35+) it would be really cool if we could somehow synthesize the lower level potions into higher level ones. I find that the level 1 and 2 potions are rarely worth my time to use or the few gold you can sell them for.

2) If you run through the mp dungons with others, to help them out, when you have run out of runs, it would be nice to still get the friendliness bonus. Its only +2 and you don't get anything else anyway....
