Cascade/Halo/DS hps and efficiency

[Rahzra]

Hello all, does anyone have some math that shows the relative hps and hpm of the level 90 talents? Since divine star has a fixed AoE cap on it, that one should be a fixed number but cascade will scale on raid size and halo will scale on distance traveled. I'm looking for something that will show the hps and hpm of all three spells in various situations (an example of these are below). Item level might have some effect on this too so assuming a reasonable raiding item level of 655-670 would be perfect.

DS
Cascade for raid sizes 10, 20, 30
Halo for average distances 10, 20, 30 yd

Also, I think I recall halo having an AoE cap too. If it does, how does the targeting system work for who it chooses to heal? I would think it only heals the closest people, which would suck. Thanks.

I dont think you need any calculations.It has been discused before and tested by people , and CASCADE by far comes the best,in every situation , healing and mana wise.
