Gravity has been somewhat neglecting their extended classes a bit, but SG is not a bad class overall. I've seen some people play them really well, if you don't like their restrictions play another class.
Zodiac wings are useful to many classes, not just mage, just find the gear that you need and work for it. Most of our custom are "all class" (except baby wings), and it is likely to remain that way.
You do sound like you are whining an awful lot, and it seems many people think so, if that's not how you want to come off then maybe revise your attitude. If you're undergeared go work for it, no one was geared from the start. I know some people create a farming char to gain gears for a main char that is more gear-dependant, that's always an option too.
