Producer John Lagrave said in an interview with CVG that the studio is content with the way things are. "[The free trial gives] a good sense of what our game is," he said. "You know, we looked at it lots, we looked at whether level 20 would give you a good sense of what our game is, and we think it does. There's also a lot of things in the game that are special that we want to reserve for our paying customers."
Lagrave pointed out that Blizzard has been beefing up the trial experience by including additional features that were previously reserved for subscribers only.
