No I would like to see a change. The current model encourages the blast and rest party mode. Currently magic users can decisvely turn a couple of battles and then they are out of useful combat spells. At that point the party becomes reluctant to preoceed further until the magic users rest.
I suspect the likely scenario will be the mage gets a basic attack at will based on reserved feats or similar mechanism and that works as a range touch attack and is as effective as missile weapons (e.g. 1d6 or 1d8 damage) and they have recoverable resources that can enhance this effect (or feats). This effect can be used pretty much at will
In addition they probalbly will get some spells that will work similar to the book of the nine swords manouvers and are recoverable between encounters. Buffs and single target save or die spells would be canditated for this.
Then they may through in a few vancian major spells that alter space time and reality on a per day limited usage. Area clearance spells, teleports, wish and so forth may fall in to that category.
Personally I would like if they made a lot of spells in to rituals, warding spells and scrying, opening planar gates and that kind of stuff should be rituals and not something that can be done in a 6 second incantation.
