I will briefly list some popular build variations <<<
AoE dealer
.Wizard3 - elementalist3 - warlock3 still great AoE. Elementalist provides multi-hits and burst AoE.
Some players have discussed about giving up wizard3 quickcast to get pyro1 to get x1.15 damage boost on fire skills (meteor) with Staff weapon. Giving up wiz3 for pyro1: wiz2-pyro1-elementalist3-warlock3/thaum3. Ice option with rod x1.15 ice damage attribute: wiz2-cryo1-elementalist3-runecaster1 (rune of ice)-shadow2/sage2/enchanter2 for stronger Hail and freezing sphere. Fire option is more popular, and froster lord card exists for electrocute.
…Sage2 is viable AoE burst dealer now and fits into many builds (2 ranks instead of warlock 3 ranks). 1 free rank, usually filled with runecaster or sorcerer1. Example pyro2 - Psychokino 3 - (sorc1/runecaster1) - Sage2 or Elementalist3 - sorc1/runecaster1 - sage2. If you use sage for boss dealer (fast saalus), take surespell to use dimension compression full charge.
Hybrids
.Pyromancer and psychokino offer AoE damage with CC. Psychokino channeled skills are worse vs boss, and great during mobbing. Pyromancer best CC is fire pillar, which is on 10s duration with 30s cooldown, cast-and-forget CC.
…Pyro2 - thauma3- sorc1 - enchanter2 god of wizard buff build getting more popular, provides hybrid playstyle with best wizard support buffs for party, and sustained damage by summon and Lightning Hands. Uses few active-skills and requires a lot of materials to cast buffs. Bad performance if your //ping is bad for auto-attack Lightning Hands.
…All builds with sorc1/2 for sustained (AoE) dps use high weapon and high SPR.
Mob grouper
.psychokino2/3 for magnetic force
…Linker1/2/3
Can combo these ranks with (SPR) chrono3 for full support mob grouper with pre-made party/friends.
Low-target Burst
.Featherfoot1/2/3 usually combo with linker to solve low hitbox size problems. Very high burst damage on Kundela Slash.
…Shadowmancer1/2 strong vs ground-mobs. Can combo with psychokino2/3 heavy gravity to be strong vs flying too.
Farmer builds
.All builds with linker2/3-thauma2/3. Link2-thaum2-feather3, wiz3-link3-thaum3, wiz2-link3-thaum3-runecaster, link2-thaum3-shadow2/sage2/enchanter2. Each provides unique advantages- sage missile hole, feather levitate and HP drain, shadow clone, runecaster giant mode movespeed and H&def, wizard3 cheap damage attributes (and some reflect shield if you like it), enchanter2 buffs. Also seen wiz2 - link2 thaum2 chrono3 speed farmer. Wiz2 link2 thaum2 alchemist3 is viable too and the most unpopular farmer wizard build.
…Necro3 builds still OK at farming. Usually combo with sorc1/2 and linker 1/2, pyro1/2, or cryo1.
If you ask my personal opinion, I like sorcerer and thauma most of the wizard tree. I never liked cryomancer and chronomancer of wizard tree.
