Have u even considered its use in mass dungeon pulls.
Lightspeed + gravity with CS=
King of aoe damage.
If they didnt nerf caster aoes then lightspeed would do so much dmg in tht 1 action.
Use ewer / enhanced to lighten the mp spam.
Ppl just straight out assume its ONLY for healing purposes cuz they like o all our dmg is dots lol

God like for stoneskinning party in fights

Stoneskin 2 < lightspeed + stoneskin.
Saving it for just heal spam is bad lol ( -25% ) kinda tells u "hey, u shouldn't be spamming tht with helios etc or else the heals will be pitiful lol "
