Cast XP is always a % (usually between 10 and 35) of the current magic level.
XP to level table usually reaches the hundreds of thousands by mid-to-late-game.
Gaining 10-20 xp vs the millions needed to level up? Not a good source.
If you want to balance the XP gains, try to even out the damage some more. XP gained by damaging enemies is the best way to level up. For one, don't use the Dark/Zepheryl summons or nm glyphs: they leech XP from you. For two, Iceblast and Multisparks are the best NM ways of damage enemies (until you get icefury), with as many + x-(x+y) to nature magic damage items (staves of survival, liveliness, animation, etc.) as you can get.
Combat Mages can try stacking Firewalls (with a 20% cheaper fire book, or the set book) in mid-to-lategame, or fire rings (don'T remember the cast delay on those two.) Slow Crowd if the energy allows it.
if nothing else works, equip your melee/ranged guys with weaker weapons.
