I play Lonewolf so my mage has all four and witchcraft, but sure air and water and earth and fire is fine.
Fire is mostly offensive damage causing spells this is really important early on and vs undead. But in some ways is not the best college, burning as a status doesnt do that much damage and ooze/poison explodes when contacted with fire so be careful around poison and oil. Fireball is a great spell for hitting a whole group of closely grouped enemies, clearing mines and destroying obstacles.
Water College is healing and ice magic also the Rain spell which is very useful to put out fires, cool lava/ground fire-zones and wet enemies for follow up ice/elec attacks, and ice attacks freezing status is great when it works, Multiple improving heals is essential.
Air College has Teleport( other) spell great for putting enemies in the lava and sending any nearby unwanted enemy to somewhere else where they cant hit the poor mage with a big heavy weapon, Tornado which can clear Lava where your gonna need to walk, Invisibility spell better than sneaking, and Electrical bolt attacks which do good damage and can stun a target which is a great effect on enemies, also most enemies seem to have better resistances to all other attack forms than air. Featherfal is also good for a few area where teleporting someone gets a player somewhere they cannot walk.
Earth college uses poison attacks for its attacks which I am not a huge fan of since it can explode, can poison friendlies and doesnt do that much damage to some enemies ( heck it heals some) it is fine against normal people type enemies and orcs/goblins but lots of stuff is pretty resistant. But Earth does have really good summons Spider, wolf, Bloodswarm and Earth Elemental, spiderrfor a lone wolf party early in the game is virtually indispensible. Fortify is a decent defense buff. Boulder bash is a good spell it bashes and poisons, most things have little resistance ot bashing damage.
Witchcraft has my 2 favorite summons spells Undead warrior and undead Armored decapitator( especially). My favorite fighter buff spell Oath of Desecration ( your fighter on this spell is really deadly for 3 rounds) and the best short-range high damage spell of all, Death Punch.
All colleges are useful, but some spells are less or more useful depending on how the player operates
