I posted this in another thread but since this is the list, here it is again:
1)What I would like to see is where your level, if they go with levels, is based on your combined skills. For example, fighting skills, crafting skills, gathering skills, etc.
Each of them can be broken down into multiple skills. Combined together they make up your level. In this way, you can become a level 100 crafter without ever fighting if you want.
Also, using items would be based on your skill. If you are a level 100 crafter and want to fight that level 50 mob, you will die in an instant because you are a level 1 in fighting.
I wish games would go this route instead. It allows you to create the kind of character you really want, not what the game forces you to make.
