.....not sure the header is the best description but one of the main problems with the Quest for me, is getting the expansion balancing right - it's difficult to play one expansion after another, with the same character, as you generally power up fairly easily, so some expansions offer little difficulty.
Would it therefore be possible to switch between different characters, so you can start a new character for an expansion, share some money and equipment, then switch back to your main, as and when, as the difficulty rises?
