As much as I thought WotC was out of their mind for declaring that Wizards would be able to have at will spells after I played a 4E demo I found that it was really useful to have 1 spell that they could use over and over. I know that Reserve Feats cover most of this, but it would be nice at early levels to allow Wizards 1 first level spell that they could use again and again to continue longer through out the day. It wouldn't be anything major, but would improve a bit as the caster leveled and at later levels would most likely get replaced by a Reserve Feat that had a stronger effect. I was thinking about something like one of the Lesser Orb spells.
Also a non-divine healing ability like the Second Wind ability introduced in Star Wars Saga Edition would be a nice way to ease the burden of healing classes. Maybe something like 1/day+1 per 5 levels. I know that 4E is also using this as well, but they've got it at 1/encounter which seems a bit much to me if you're keeping cleric spell casting.
Other than that this looks great. I had started to get pretty excited about 4E's launch, but I must admit Paizo makes the best adventures I've seen in the 12 years I've been playing D&D. If the Pathfinder RPG is what you're going with for future Pathfinder adventures that will definitely factor in to my decisions on what I use in the future.
