Question on Scholar's pet

[givemeraptors]

Why don't we just stop bickering about everyone's bad math and say what kind of content you'd use which fairy in:

Coil 1-5: Selene unless solo-healing, or if the party is derpy and/or undergeared.
Primals HM: ditto
All roulettes: again, ditto
Primals EX: Eos, maybe Selene with good party
Coil 6+: ditto

See the pattern? If you're overgeared and/or echo buffed for the event, Selene, if not Eos.

Honestly, even EX primals can easily be done with Selene.

I'm not seeing what isn't relevant in anything that I've said. OP wants to know when to use what faerie a given situation. And whereas selene does give a small dps boost, it is always safer and overall more efficient and both you and your healer's part to use Eos. Go parse yourself doing titan with the same group, at least, 10 times. 5 for eos and 5 for selene and see for yourself how minimal of a difference selene makes in overall dps vs healing throughput. I'll run the tests myself if I really need to.

Healing throughput is not in the slightest way comparable to overall DPS. I hate to break it to you, but if you don't understand that you are a terrible healer. Overhealing is always wasteful. Excess DPS is always useful. You're talking about raising your party's survivability from 95% to 99% That means nothing to me in the face of a DPS increase (however small). And there is no fight that should result in TP starved melee DPS except T8 (from what I'm reading, haven't done it myself).

Honestly, just use your head and learn to use both, even in the same encounter.

This is also totally viable. Doing this is no different than a SMN whipping out Titan when gaolers appear during solo tank/solo heal TEX and resummoning Garuda when they're dead.
