The weapon idea to me, is a bit flimsy, I don't see how a little stick could become a weapon, unless you fluff up the ability to use the magical energy therein, but that, to me, would cost charges...just not what I wanted to do with the class....
easy, the energy needed to make a basic blade is so minimal it is not missed. or, the wand adept can work the wand with that much more efficiency, getting an effective 1/10 of an extra charge they can make a light saber with.
wand opportunist looks fun, and could quickly be broken by AOOing with a disintegrate. giving a legitimate weapon is better.
However, I do like the Warlock idea...that is awesome.
everything is better with warlock.
