Earthquake and Storm are decent for their mass CC, but once-per-battle and require an obscene amount of AP.
If you think meteorstrike and hail attack are impressive, or that spells like flare and blitz bolt do "good damage", you haven't properly leveled a ranger or warrior. 1500 damage crits at level 15 are not uncommon. They don't lack for AoE options either, between Whirlwind, Battering Ram (aoe knockdown), Ricochet, and poison cloud arrows (so cheap and common to make they may as well be free)
