You can change classes unlimitedly, but the experience required to level doesn't reset to 0 (ie if your staring at another 50,000 exp pts to level from say 7 - 8, your level 1-2 in the new class will still take the 50,000 (maybe more maybe less, depending on whether you are switching to a stronger class). The benefits that you could get from chopping and changing in Wiz 7 simply aren't there in most cases. You need to get strong spell casters, bards, and gadgeteers up to like level 18 - 24 to take foull advantage of their potential.

I am expecting to do little or no multiclassing - maybe a little between rogue and bard at early stage, maybe taking a developed mage late in the game to psionist.
