Prior my wizzy was a Linker>Chrono>Sage
Chrono was my fav class before and still kinda is also interested in sage and am willing to peep Alche too
What are some good builds for a Support Wizzy and WHY
Also what does Sage actually offer, it looks a little confusing as to why Id pick it
Chronomancer - Alchemist - Sorcerer to help people with long cooldowns and SP pot addiction (Sprinkle SP Potion and Summon Familiar).
What about Psycho>Sage>Alch or Chorno
Alche/Chrono/??? is going to be your support core. The last class can be Featherfoot for more healing to your party through Blood Bath, or an AOE crowd control class of some sort. Onmyoji is a good one as you can use your SP pot sprinkle to fuel Genbu Armor.
