the 75 day time frame imo is to hold novus till 2.3 when a few things happen with the ilvl increase...

1. 3rd coil. new higher allagan wep.
2. ramuh. new ilvl weps.
3. possibly another type of wep that you can get from tomes/coil that is just under the new allagan wep kinda like the unidentifieds.
4. the new relic upgrade which will always be a grind.
5. number 2 and 3 will probably have an upgrade mechanic like mirrors/sands/oil type

coil = skill/rng, ramuh = skill/rng, possible random tome drop wep = rng/skill/grind, relic upgrade = pure grind/rng

being that atm the choices are coil for 2 weps, levi for 1 and mirror, and the relic line. relic is fine being the pure grind wep. besides, you dont NEED novus to beat whats currently out atm and possibly wont be 100% needed till 2.3 and even then i bet you can still get by with whats available for awhile.

all complaints come from: "It takes too long, i dont want to run coil, and I want it now"
