It's flawed in the sense that I've intentionally skewed that scenario where it shows about equivalent HP/MP balance comparing DPS mitigation versus raw healing output and omitted a few more assumptions. For the majority of the time, the HP/MP efficiency should favour outright healing versus DPSing as a healer - though it is kinda hard to beat 0 MP consumed on SCH when Fairy and Lustrate can heal an entire instance.
Additional, to maintain that kind of damage output in the above scenario from a WHM, you will most likely need a Divine Seal'd Medica II and Regen. This HoTs would partially counter balance the oncoming damage since you would get something in the realm of 700hp/tick with my above scenario, so around 4,200 HP back in the 18 seconds. Then you'd have Benediction to fall back on as well if that was up, so you would build your chain-Holy around that scenario.
Shaving 25 seconds off total kill time isn't unreasonable, though might be a high end estimate depending on the group tier. For example, here's the final two packs of trash in Keeper of the Lake.
Total DPS is 1,382.22 over 90 seconds is 124,399.8 damage. If you remove the WHM from the equation, the total DPS is 909.1. To meet the same damage, your group would need about 137 seconds, which is 47 more seconds (23.5 second per pack).
Overall, healing will net a higher HP/MP efficiency. However, if you're sitting on so much MP anyway, why not go burn some to help the group along? Just know how not to overextend.
That's the beauty of healing - adapting to the scenarios given to you and building yourself around them.
Man, if you are CONSTANTLY (which I highly doubt) running into these kinds of healers, I'm glad I'm not on your data cluster.
Agreed after one adds a bit that "the Healer is only DPSing." It's possible to maintain high Cleric's Stance up time at little detriment to the party, but that's both dependent on the skill of the healer and tank.
There are a few variables to attest to this. I can personally do this with little repercussion to this with my party or myself and not get any hate as the tanks tend to know "OVERPOWER/FLASH SPAM TO HOLD HATE". Of course if you're doing this for single targets... well, yes, you are terrible.
Agreed.
Such as DPSing when no one is immediately in need of healing arts.
I feel the cards will provide a buff will be independent from the restorative spells. These restorative spells, I feel, should be affected by the stances that Yoshi-P seems to be touting. I expect spells to be similar to Cure, Cure II, Medica, Succor, Adlo, Esuna, and Raise and the buffs to be more unique. It would be interesting if the card buffs themselves would be affected by stance, but I get the feeling they won't. Would like to be proven wrong in this regard, however.
