I can only see this as being a good change. I really doubt lack 4e is hurting right now, but it's easy to see that the GSL was causing an already bad rift to get worse, and hopefully this can help patch it up, as well as allowing 4e fans to play the games they want with the 3rd person parties that want to join in.

Psionics are too sci-fi, not like the traditional method of spell casting that has existed only in D&D, involves research, laboratory work, and formulas, and was cribbed directly from a series of science fiction novels. I mean, come on, calling forth the power to alter the world from your own center of will? That's not magical in the slightest! Not at all like my wizard's spell "Telepathy!" |
