That's a surprised. I thought you may have held the same "Go be a WHM" sentiment that the OP had.
Oh really? If I take this literally, all a SCH is doing is spamming Physick and without a care to use the other damage mitigation abilities would yield NO time for DPSing because the SCH would not be creating that opportunity to find a comfort zone to do so.
Shenanigans. SCH mimimal effort does not and will not yield any higher DPS over any DPS unless all they are doing is spamming AoE attacks. For every 4 ticks (12 seconds) of damage from dots, any DPS could effectively deal the same amount of in 2-3 weapon skills (4-6 seconds) without taking in account crit damage. If you want to throw in bane's dot spread, how often does a SCH actually have time reapply dots consistently? Even more so, the only way to pull up respectable DPS numbers over a short period of time (Not even a full minute) is to throw in Broil, Ruin II, and the tabboo use of energy drain, if you have the breathing room after throwing down dots.
I am calling shenanigans on this too. I'm not going to say it's not impossible to go an entire 15 mins without ever healing... under the condition that your tank is not making large pulls. Example, Neverreap very first island has 5 mobs with that can all be easily tanked with as long as the healer is focused on healing until the wamoura and on other is dead before even thinking about having the breathing room to throw down dots. If you have a tank safe pulling the entire way, you have more time to DPS, but clear slower. I thought that has been proven with speed runs in 2.0. And speaking for myself only, I prefer my tanks to make large pulls because I am not only confident in my ability to heal through massive damage, but because I am far more engage doing what I enjoy about being a healer than the reason why I avoided playing a DPS as a main job in the first place.
I really want to agree with this, I do. Healer DPS on trash mobs will probably shave seconds off the end time, and minutes off the end time if there is enough DPS from the healer going in on the boss. But I have NEVER heard of healers lack of or even minimal effort towards DPSing becoming a sole reason or even part of a reason why a dungeon wasn't cleared fast enough or cleared way too slowly.
That is.... pretty inaccurate considering both in the made up statistic and the fact that you believe Lustrate has been nerfed that it's useless.
These are the things we know to be true. Learning curve for playing SCH is higher than WHM. It is higher for people who have been use to playing other jobs for longer periods of time, or even for the ones that didn't choose SCH as their first pick to do dungeons while doing MSQ in the beginning because it's so easy to just blow through them to level that you can pretty much stick to DPSing with no thought of healing or mananging your fairy from low levels.
Another thing I have realize is that some of us are so jaded, like the OP, that we forget that people will play to what is more comfortable for them because a good majority of players are, and I mean this in the most unoffensive way, casual players, may even be their first MMO.
I find it odd that I'm taking this stance because I mained SMN in FFXI and was bottlenecked into a much weaker WHM when I actually wanted to DPS. And as an endgame SCH in FFXIV who actually, I understand the importance of DPSing and how seconds, not minutes, can make or break a clear, the demand and obligation for SCH to DPS, to a degree, does not exist. And at any point as a SCH, I feel like my DPS is a necessity in a dungeon run that the party's overall success for not just a timely clear but a successful clear in general, I may as well drop out because I've done that before. I have a very instance of that that I recorded on my PS4 where I had carry DPS failing at both DPSing and mechanics by having to work over time in both healing and DPSing myself. I don't need that type of stress playing this game while doing something that's suppose to be that simple. No one does.
