http://en.wikipedia.org/wiki/List_of_prestige_classes says Sorcerers should also get Archmage.
Also a suggestion for Sorcerer in general would be no need for the Eschew Materials metamagic or components.
Also look at "Wings" on http://www.dandwiki.com/wiki/Dragon_...stige_Class%29
It says you can get a pair of wings to fly at your run speed. Warp Time flight woot! That'd be SO COOL!
Imagine if you got thrown off of an Epic Tempest's Spine (if they made one) you could be like "nu uh!" and fly back around and throw like Polar Ray at him and omg flying would just be SO COOL!
Just patch all the quests where flying could be abused. This should be the dev's new #1 goal. Flight.
