-dispel removes all spells on yourself, and you can -dispel with a particular name to remove specific ones.
However, the only way to remove an aoe spell is to rest. This is pretty unfortunate if you want to use aoe spells and then not wait 3 minutes for the not-party-friendly spell to disappear. So I propose:
-dispelaoe
This will remove all spells that are persistent aoe spells such as:
ESF Abjuration ward/ward teleport
Cloud spells
Wall Spells
Tentacle spells
Wild Mage volcano
Grease
Entanglement spells and spike growth
Caltrops
Acid Bomb
Rogue Grenades
This will make it easier to RP with people that were subdued with aoe spells (so they don't die from them), as well as in PVE when you want to loot the dead.
