More examples of utility powers, from something other than a wizard, plus more information on them in general. Martial characters' utility powers would be cool to see.
I see that most of the wizard's utility spells in the fan-made preview are Daily, but at level sixteen there is also an Encounter utility power. Are there limits to which you can take? Could a character load up on Encounter utility powers so that they always have something useful (although not as powerful) available for use, or do they have to take a mix? Presumably, one character could load up on Encounter utility and have seven extra powers per encounter, while another character could load up on more powerful but less frequently used Daily utilities and have seven extra Daily powers... could this affect game balance? They're non-attack, but still useful in combat: Dispel Magic, Displacement, Fly, Greater Invisibility, etc.
How does this affect the "fun factor," as well, when one character is able to reuse his utility powers every encounter, having a larger variety of things to do, and the other guy feels he has to save his up for the "big boss fight"?
Also, are there At-Will utility powers?
