yeah, as much as ruby set is appealing, it's not a good idea to get it now. People are foreseeing 2.5 to come really soon (like, end of December), and should bring i110 accessories for crafters, which will pulverize any accessory available now for tanks (and progression groups). They are likely to cost a hell lot though, so yeah, keep your money safe and pray for the crafters to put decent prices this time.
