Yeah, there's a balance to be struck.
– mysterious, strange magic is fun
– it does get annoying to keep running across schmoes who arbitrarily wield magic that is inaccessible to you
– it makes sense & is fun to have some strange magic become accessible to PCs, after they run across it
– in 3e at least, this isn't really feasible if you are using different systems to generate your "strange magics", since in order to pick up the magics, the wizards would have to retrain or multiclass, thus losing power in order to pick up new freshness
I can think of a way to patch this in 3e a little (using shadow evocation etc. as a model) but who knows how this would apply to 4e at this point.
