Hide/walk in shadows, tactical retreat and Fast track have replaced Aerothurge invisibility, Cloak and Dagger-scoundrel and Wildfire-pyro since the AP costs are less and they are available as non-spell user college skills, heck 1 level in Scoundrel and 1 level in Expert Marksman just for those is well worth it.
I have been using touch spells a bit more than I was with my Fighter/Mage since it is often oppurtune to do so, since I find myself in melee range a lot.
Oh man I feel the chagrin at unspent talent points!
