I was thinking about creating more sets of abilities for each arcane school in order to include the several roles that a wizard for that school may play. For instance:
Conjuration School, the specialist bonus gives you protection, the 1st level ability is damage, at 8th level a teleportation movement and on the verge of epic a summoner mastery. It could be cool to have a general set of abilities to represent the all round conjuration specialist and some groups of still more focused abilities. Only for conjuration I could say Summon, Teleportation, Protection and Barrier, Area Spells...
What people think about this??
