I heartily disagree. Every mode has it's own seperate character, it's own colour, regardless of what scale it's from. They're like their own chords. I'd say it's beneficial to learn the harmonic and melodic minors too, as well as all of their modes.

It just doesn't make sense to me that anyone would be violently opposed to learning scales, especially seeing as their constructions are symmetrical, as well as identical to chord makeup. I'm not knocking Kirk's method, don't get me wrong. Just don't lock any doors before you know what's behind them.
