On Wizards:
[Angry mode]WTF??!!, they just took an awfully bad decision, you shouldn't give tactical flexibility to wizards! that is the sorcerer's schtick!! and results won't be nice, they were already halfway there with reducing the number of slots, all they had to do was to allow for more flexible traditions and to allow more freedom on picking a signature spell and at wills!! What they have done is like demolishing a wall just to fix a broken window!.
They have just given wizards way more power than they have had before, in order to balance them they will have to decrease the spell's overall usefullness which will hurt specialists. This is just the worst thing that could happen, if wizards are that good, the sorcerer will suck great time, unless they bump them and by a wide margin (and I'm talking about a godly improvement). Nothing good will come out of giving wizards both tactical and strategical flexibility, nothing!. [/Angry mode] (If you don't beleive me, play a 3.5 batman wizard with that provision, that you can spontaneously cast from your preppared spells, and tell me how it goes)
