WHM DPS needs to stay this high.

[LegoTechnic]

The problem with creating new healers, is finding ways to make a different healing archetype that ends up roughly balanced with the others. We got the Raw Healer(Whm), the Sheild Healer(Sch), we don't really have a true Regen healer but SE kinda sees Regen as Whm's thing currently. Ast was kinda a Buffing healer. So you either need to put a very unique twist on one of those, or come up with something new entirely. Its also kinda why new styles of Tanks don't show up all that often. There is a little bit more wiggle room for DPS, but even then you do hit reskin territory fairly quick.

The entire problem with healer balance is that they tried to copy DPS balance in the Healer classes, and became determined to make WHM's the analog of BLM and a class that didn't need to buff.

Originally you had WHM who had powerful heals and regens with passive mitigation and SCH who had powerful active mitigation and passive buffs but poor ability to heal large amounts, especially AoE. When HW roled around, they introduced AST which was a "buffing" healer, with minor role-switch options in regen and shields depending. SCH in turn already had a similar minor-spec option with fairy choice, being able to choose either a regen fairy or a buff fairy while keeping shields and mitigation as their primary calling (damn do I miss Virus). But when it came to WHM they decided to keep it as the traditional analog to BLM, presumably out of theme. BLM has never had any real party synergy abilities, and is for the most part a completely selfish DPS class that in compensation deals very high DPS. Its main drawback is that it seeks to be immobile, whereas other selfish DPS like MNK or SAM have the drawback of "too many melee in the crowd", which is often equally detrimental for mechanics, but since BLM can stay at range and most groups run two ranged spots, it found a lot of party value regardless.

Thus much like how BLM is the completely selfish DPS cannon that specializes in personal damage output with minimized mobility, its analog WHM was the selfish healer who forgoes party synergy and instead offers the biggest heals and less mobility. This was rather obviously their original design intention in HW, and its actually been stated that they wanted WHM to be "heal-focus" by design, because rather than give WHM a party buff of any sort they instead chose to nerf Selene and proceed to over time to try to balance healers that could party buff with one that can't. And naturally players tend to hate it, because healing a fight is completely different from DPSing it with completely separate goals and ceilings; there is no ceiling to DPS as long as aggro isn't an issue and the more the merrier, but with healing you only ever want to heal what is needed, as overheal is considered "a waste". Thus in progression party selection (because let's be clear, that was the only place any of this mattered), it became a very similar issue that MNK and later SAM found themselves in where they were competing in the meta against DRG, who had the useful pierce-damage debuff that the mandatory BRD/MCH required, and NIN with their Trick Attack. Because too much melee could make some spacing mechanics more difficult, there were often only two melee DPS slots to fight over, and while some groups did run three melee they were not typical.

As long as they adhere to this design philosophy players will never truly be happy. Despite having the strongest heals and the highest damage potencies WHM will always feel neglected as long as the other healers bring buffs that the other 6/8 raid members find to be more valuable, especially if they contribute with faster encounters. Additionally as long as they try to instead impose "value" for a pure-heal class by reducing the effectiveness of buffs, which has not only led to the gradual and complete death of Selene but the general neutering of the AST card system, then the identity of a "buffing" healer will continue to suffer. If the intention is to bring healers to a point where any healer combo can handle combat with minimal favoritism, then WHM needs to be made separate from the BLM design philosophy even if the two classes are iconically mirrors, and given a "buff-role" switch similar to SCH's fairy choice or AST's stances. Something that takes away something from their kit, but adds party synergy that the 6 out of 8 non-healing party members can salivate over. Only then will they be able to allow healer buffs to both be meaningful decisions and something the playerbase can feel good about.

And this will remain true no matter what they do for a "new" healer, be it debuff, haste, reflect, evasion, or whathaveyou.
