...you do understand that it's impossible to answer your questions without posting proper setups? It's impossible to say what Gems are you gonna use for SQ/NG sets unless you post Weapon/Accessories/Sub-Equip as well as Elemental Damage enchants you're using. Same thing with what Infinite Avarice accessories to use. Infinite Source of Avarice is not worth it even without Lv.90 Epics, unless you've already upgraded all other Avarice items and got yourself usable Savior. Obviously, it's even less worthy when Lv.90 Epics are added.
