Pet buffs?... I wouldn't put it past most DF scholars to set their pets on sic, in which case pet buffs is one less thing they're doing themselves.
Okay. Then, let me ask you something. What do you think of the following skills: Second Wind, Bloodbath, Manawall/ward, Equilibrium, Clemency?... And besides this, literally all defensive cooldowns in every job ever. Is this optimizing or min maxing? I wouldn't say so, no. Since people have access to these skills, they should be expected to make full use of them. Some of them restore HP (looking specifically at Equilibrium and Clemency), and means a tank could potentially save themselves if the healer doesn't react quickly enough. Now, they are not healer jobs, right? Why do they have these skills at all then?
Is this also combining two classes? Or are these skills meant for solo content?
EDIT FOR WORD LIMIT:I would also like to point out that you're seriously underestimating a healer's ability to dps, specially in large amounts of mobs. As scholar, I can place my fairy in a set position, set up rouse+whispering dawn, use a mouse over embrace spam macro and I hardly have to bother with healing for a while (let's assume for a while that your tank does use his/her cooldowns as they should be used) - now, I have at my disposal 3 dots which I can spread out with bane, shadow flare, and miasma 2, AND blizzard 2 in case the fact is indeed taking negligible damage.
I won't post maths or graphs, but do you actually believe our DPS is negligible? If so, I'm sorry, but you don't know/understand your skills.
Also, it might be that you have indeed very potent healing spells - they still won't be used for much if you're overhealing.
Now, as I've said before, you're absolutely, undeniably allowed to play however you want - but don't try and convince others than you're doing anything besides a mediocre job.
EDIT BECAUSE I REMEMBERED THINGS I WANT TO ADD: I would also like to point out a few things - mostly because after reading a few more of your comments on this thread I believe you lack the confidence to stance dance, I assume because you've tried and it didn't go well.
1) No healer is immediately able to perfectly stance dance and optimize all their skills at the drop of a hat - most of us have caused quite a few wipes in the process of learning (I still do derp sometimes).
2) You don't need to use CS to dish out some DPS! - if you lack the confidence to use CS, try out using some damage spells in dungeons and roulettes, just to test out and see how comfortable you are with letting the tank's HP drop, and such.
3) As a scholar, it's useful to try and place your fairy in a set position when you can, because fairy AI is set to prioritize following you instead of healing. As such, if you're in the middle of a pack of mobs and have to focus on avoiding AOEs, it's a lot of downtime for the fairy - instead, place it somewhere close to the tank and have it follow it again when the mobs go down.
4) Practise rotations in striking dummies! They're great help for us healers too!
5) Listen and pay attention to advice randomly given, even if by people in DF - I started maining schat the start of heavensward, and at the time I had minimal understanding of the job. Most advice I've been given, was given to me not by FC mates or friends, but people I did comtent with - a random DPS that once mentioned I could sub in aero to add to DPS (at the time I had surecast /rolleye), someone once commented that if the tank was squishier than normal I could set down sacred soil, cast dots and bane and THEN cast shadow flare (by this time SS will have worn off so it's not a wasted AF stack), and so on.
6) PRACTISE
7) PRACTISE
8) PRACTISE
In case you really just don't like/want to DPS though, as I've pointed out before - it's up to you to do it or not. You're free not to, like those tanks (that I absolutely despise) are free to not pop a single damn cooldown, and rebelious BLMs and BRDs can ignore all their HW skills and choose to ignore enochian and WM and stick to their old rotations. But when I'm casting something every time I can, and using all skills available to me, I can damn well feel annoyed at them for such behaviors.
I honestly do not know how any healer can stand to run instances like expert roulette dungeons without DPSing though - I do not mean this as an insult; it's just that the healing required is so little, and the content so predictable and repetitive, I'd be bored to death if I didn't dish out some DPS.
FINAL EDIT, REALLY I SWEAR: tl;dr play however you want, others will do the same, some will gree other will not, you might get kicked or you might meet people who sympathize and you'll make new friends. Not DPSing doesn't make you a bad player, perhaps a less active one, but some people just won't care, overall it's more important to have a good attitude toward people - if they comment on your playstyle, DO NOT SNAP BACK. Explain that DPSing is simply something you don't like to do, or that you don't feel comfortable with. High chances are, they'll be chill with it.
