I played a single playtesting session that was essentially just a big fight. Nobody at the table seemed impressed. Takes aspects from FATE, takes daily/encounter/at-wills from 4e, has a bunch of fiat-based abilities a la Ars Magica. None of the mechanics for the characters were particularly fresh or gripping.
I played the bard because they wanted feedback on it. But it couldn't really do much of anything, seemed to ostensibly be a support class, but was patently inferior. It also had that annoying 3e and 4e dissonance where martial characters seem to get the best of all worlds: excellent armor and damage adsorption, while still hitting as hard as any spellcaster.
It also had that 1st edition feel where the softer characters felt like they were at the DM's mercy in regards to deploying ranged attacks, because there's no rules for cover and distances are completely abstracted. In such a system, should there be soft targets?
The escalation die is a step in the right direction, but it would be better be a resource characters (notably support characters) build up rather than just a handout that inevitably turns battles to their favor.
Like I said though, it was one shallow session, and I'd like to see future playtest revisions.
