I enjoyed it. I created a ton of characters to test the classes out--I'll definitely be starting out as a Necromancer. Like Cutter said, it's going to be a good game to jump in and out of, which, with no monthly sub, won't be a problem.
They really need to tone down some of the combat effects (Fire, anyone?)and work on just how squishy the pets are. The event system is fun though, and before you know you've rolled along for the last hour just by getting caught up in what's happening around you.
