I've been running the Tactician/Trickster that I cribbed mostly from knownastherat upthread (thanks for that by the way). It's super fun, but probably a lot less powerful generally than the Battlemage version. However, I'd wager post 10 or so it does a lot better when you have a small amount of melee enemies to face, since you can keep them perma-distracted.
I kind of want to try out the Battlemage version as well but may end up doing chanter/wizard instead.
