Is Quicken a must of Sorcerers?

Its a "nice to have" (if you can fit it in), but not a must.

Both my sorcs run without it. The biggest down-side is that even with a high concentration (50+), you'll fail some concentration checks in some content (epic quests/raids). That means you'll have to rely on tactics (body position, jumping, timing) to fire off critical spells (self-heals) without fail.

Hell... I've seen "success!" and the spell was still counted as a fail. They have coding issues still. Just really dam hard to get it to replicate to get them to fix it.
