Would greater flexibility help alleviate the problem?
Lets say that instead of choosing Encounter and Daily powers, your character could instead use said number of encounter and daily powers of your level. At each use the character could use any power available to the class. For example, a 1st level PC would not pick 1 encounter power and 1 daily power; instead they would have 1 use of each per encounter/day. When they use the power they decide which power. (This could also make the latter 3 multiclass feats seem more worthwhile to those who question their value by having the feat add one power of the type to the available powers instead of replacing.)
This could be totally game-breaking, but might be worth some playtesting to see if it helps increase variety.
