Are you at complete Novus already? You're saying you're yet to see "real coil" and if you're not I wouldn't have even bothered if I were you. It's such a massive timesink and for what? Get Soldiery weapon if not now then in the first days of 2.4, and then get the reachable i115 which will probably go to Shiva. I absolutely regret undergoing the grind to Novus even once.
My fear so far is that the potential 2.4 meldable gear is going to simply make materia prices rise even further. What a pain, an ideal novus seems so expensive for something that might just be made useless by a primal drop. I still do sort of want that nexus light saber though if only for completion's sake.
