So how is whm doing?

[Allegor]

At level 80, I was 1 shotting a lvl 50 mob in the open world with my dot before the squish.
Now at 90, I do less than half of it's hp.
"you will not feel a difference after the squish" they said in the live letter....
Thank you square enix. Thank you very much. /sarcasm

Never had mana issues or lacks of heal potency though.
If you have to heal A LOT (and therefor have mana issues), it means your party members suck at doing mechs. Not your fault.
Liturgy is OP if you know how to use it.

To be fair, if it's on WHM, that's not [entirely] because of the stat squish. Aero/Dia's initial damage was literally cut in half from 120 to 60 potency
