This is great news.
Make a Wilder//Sorceror. Between Schism, Arcane Fusion, and Arcane Spellsurge (kicks in at level 14 I believe), you will literally find yourself shitting extra actions.
Lemme give you some perspective here:
Schism allows you an extra mental action per round. Say, a stilled, Silent spell, or a Power
Arcane Fusion casts 2 spells at once.
Arcane Spellsurge casts all spells as quickened.
Any metamagic increases the casting time (say, Invisible spell, a +0 enhancement), allowing you 2 spells/round right off the bat right there.
Linked Power allows you to practically double your output of powers.
So in one round, after you're buffed, you could cast a linked power, a quickened spell (preferably an arcane fusion), an invisible spell (another arcane fusion, sir?), and you haven't even started polymorphing into a choker yet. Not to mention you have a deep well of power points and spell slots which you can use like a teenager uses tissues.
Could be lots of fun for a blaster caster! I don't even want to think about how this combos with a Swiftblade/Factotum..
