I did not say that nor did I imply that. I suspect perhaps we're talking past each other at this point and failing to see each other's ideas.
Let me try to clarify my position, yes? I don't think psionics can work reasonably in the current system for most of the same reasons it didn't work in 1e: too flexible and powerful to keep things challenging and fun for all. The number of ways to work magic is not the issue for me at all (though there already are at least three distinct ways of casting magic, not just one); the issue, rather, is that the kind of flexibility psionics bestows is too great for them to balance well in a system where (IMO) flexibility is king. I mean, isn't flexibility what makes the bard the bard? And isn't the bard the one that everyone else loves to hate for just that reason? (Though I actually like bards myself...)
Like I said above, we've been toying around with different ways of taming the mystic class, but so far the age-old problem has remained: either I have to make them so weak that they're mere support staff, or else just beyond that point they suddenly become too powerful and leave everyone else in the dust. I don't say this cannot be fixed; I only say we've tried to fix it, and so far it's a no-go.
