Air - Spiking on one target. Tons of damage to fry 1 opponent at a time. Armor penetration and knockdowns.
Earth - Defensive. Wards, armor buffs, selective damage (Such as KD Aftershock: Alot of damage, only under specific circumstances) and a fair amount of nuking.
Water - Hex category. Limited damage and AOE damage. Slowing enemies, annoying hexes and selective damage. (Vapor Blade, Ice spear) And one elite ward... because people don't use it.
Fire - Massive AOE spells on multiple targets. Nuking. Each spell inflicting well over 100 damage, usually on multiple targets. Nuking, limited spiking, Elementalist degen, nuking, high damage, defensive damage, nuking.
I think we can generally agree on that, if that is the case why are there no Nuking elites? Mind Burn, Double Dragon, and Starburst. BAH!!! (The mind spells shouldn't cause exhaustion anyways.) Where is my:
Fricken Dragon Fart - for your entire life, all foes in the area take 10-50 fire damage each second. (10mana / 3 sec cast / 30 secs recharge) (Attribute: Fire Magic, idiot)
(Well, that may be a bit overpowered, not the damage, but the name... the name is too overpowered

In fact, where is my "In the area" nuking spell to begin with? I think they need to add some fire spells which cover "In the Area" radius, or even bigger! And for craps sake, GIVE PRYOMANCRES NUKING ELITES! Earth has an infinite amount more of nuking elites then Fire Magic, AND IT ONLY HAVE ONE OF THEM!
