I'd like some more specific information on the customization of powers. I thought the game was going to be all about making the character you want but when I read the articles here I got more of a "dual-class" feeling.

Am I stuck with the powers that are put in each of the power sets? Are you able to choose powers out of those sets instead of being stuck with those and only those? How customizable are they? Can you get bonuses added to the powers you like? They are upgradeable but that just sounds like you go from set power a to set power a-2 with no decision making or choice available.

Finally, I'd like more details on the visual effects of the powers and how much you can change them. Thanks
