I don't do savage raids but isn't weekly tome gear already enough to do AAC Light-heavyweight Tier savage raids when item level requirement to do M1S is 700, M2S is 705, M3S and M4S is 710 while weekly tome gear item level is 720 which you can upgrade to item level 730.
And not forget that now you can get item level 710 armors and accessories (except the second ring) with no weekly limit from AAC Light-heavyweight Tier normal raids.
If you don't want spend +20 million gil for crafted gear set, then just craft them by your self (note that i don't know how hard it is to craft best level 100 crafted gear when my crafting jobs level is between 60-90 and i don't like crafting in general).
Crafted gear being "expensive" is not entirely crafters fault when it's RMT's fault that destroyed economy back in patch 2.0 and since then the economy really haven't recovered.
And getting gil is really easy these days when there is many ways to get high amount of gil and even doing some daily and weekly stuff gives you decent amount of gil.
