The Galactic Command system, with all its flaws, made possible for me to gear up four or five toons to BiS for the first time. It took very, very long, and then they made Ossus, and then they announced 6.0.
The gearing system had a good run in the post-5.6 meta. I don't think I'll get on the gear treadmill so soon again. In fact, I'd rather they completely remove gear from the equation, but let's face it, it ain't happening.
