Whm has 400*3=1200 heals from lilies every min plus 1200/min avg healing from asylum and assize. So 2400 total.

While Ast only has 700+500+200+720 from celestial, collective horoscope, and star which total 2120. And 1000 of that is regen which is not always useful.

That is not to mention lilies have charges so it is always reducing cd while Ast cds will stop so it is even less frequently if you need to hold it.

It also let you have instant cast to move whenever you want while Ast can only use lightspeed at specific times and it is hard to use it outside of buff windows.

20s is too op.
