I'll start by saying that all of the writing is top notch and that the production values in this PDF are amazing. The look and feel of the product makes it seem like the classes pages were actually an ommitted part of the players handbook. I also don't have any doubt that this is a fun class for the players.
But there's a galring, gaping flaw. This class is completely broken. Having unlimitted teleportation starting at level 1 is completely unbalanced and not fun for any one else at the table, especially your monk who gets a limitted use, limmited scope teleport at a much higher level. Worse yet is that the class didn't really lose anything else with the levels to compensate. It progresses, at minimum, at least as well as any other class without factoring in the unlimitted teleport (which gets more and more broken as the class levels).
I understand that he said he playtested it and his players loved it.... Of course they did. They got to play an OP class.
