Anyways, the point of this little game is to basically state how your healing spec would be played if you had designed it. What would you do differently?
How I would have designed disc:
1. We wouldn't get any actual healing spells. Penance would still be in but as an offensive spell. Atonement would still be our AoE heal (with penance in the rotation).
2. I would totally change how absorbs work- our heals would be more bubble based. Here's how:
Absorbs would still suck up damage, however, once the divine aegis/shield/spirit shell was counted as done absorbing, it would heal the target/targets for half the amount absorbed.
a. Spirit shell would be on a 30 second cooldown. Would still be able to be used as an AoE in conjunction with POH (POH would be considered a non-heal for disc, only used to spread SS; maybe keep flash heal for a single target SS). Upon ending, it would healing everyone in the group/raid for the amount absorbed. I would maybe even get rid of spirit shell itself and have one for AoE and one for single target- that would get rid of POH and FH all together.
b. Get rid of glyph of PW:S and make the heal on it baseline.
c. Divine Aegis would be an actual physical spell- not the RNG it currently is. It would be our tank cooldown and have a 2 minute cool down.
d. We'd still have our PW: Barrier, it would still function the way it does to help out the other healers in our group, but it would absorb XX amount of raid AOE damage and upon ending, heal those folks for the spread amount absorbed.
With it this way, we'd still be using Atonement healing, but it would actually empathize on bubbles.
This is how I envision disc playing if I were designing the spec. Disc would be really nice on spike/burst damage type of fights, but not too underpowered on non-spiky fights.
