Those things, i would miss...dearly so...but that is the dilemna, everything else seems superior...which is why i'm hoping to see other peoples opinions...
You have basically two options:
Either get more abilities as a warrior, being able to attack with weapons, wear armour, withstand more injury....
Or stay a better spellcaster, with a spell list much better suited for adversely affect others (whole-sale destruction of enemy groups, force conditions on enemies that really ruin their day, and get a lot of great protection spells).
What do you see yourself doing with the character more often? Wade into combat, probably buffed to the ear tips with magic power, or unleash megathaums worth of magic power directly on your enemies?
That's the big question. If you answer that, you answer what class you should go with. Because nothing else really matters - if you don't need to be a warrior, the better BAB and other combat stuff doesn't help you that much, and if you don't want that much magic, the better spell list doesn't really matter.
