Just level to 80th...
Don't worry about gearing, while you have RAF... unless you're done leveling toons.

Once you're done leveling...
You'd gear at whatever level you want to play.
If you want a 70-74 twink, at 70th, that's fine to gear at that point.
Ultimately, if you're planning on end-game, gear means nothing until you're 85th.
