discoking, i think you kinda missed my point man.
you sound very uninspired (not saying that as an insult), so you just figure you "might as well become a more well rounded player" by being able to pull off exotic stuff.
i mean, if you are not inspired and don't have a clear direction of where you want your playing to take you, it won't matter even if you'll have the biggest skill set in the world. your imagination and creativity need to drive everything else, and not the other way around. that's exactly what makes all those youtube player wankers. it's like trying to paint without knowing what it is you're trying to convey, but you figure you better work hard on your photorealistic painting skills.
what matters is telling a story, expressing yourself, being your own man through music.
it may seem easier to just buff up on scales and technique, but it's a dead end. focus on becoming excited about what you do, no matter how. the rest will fall into place.
