More like I'm trying to be explicit while you are not.
Your presentation has a slight spin to it which implies states that because only 2-4% want less, we can infer from that (implying) the other 14-18% are ambivalent (a statement you made, even though I directly rejected it in my own personal case), and so wouldn't mind too much if more attack buttons were put into all the Healers. You even say this part in various ways, such as:
...which I specifically just quoted to you. This is an incorrect interpretation.
In other words, your position SEEMS TO BE:
1) Only 2-4% (depending on Job, but overall probably 3%) want less damage buttons.
2) This must mean the other 18% of the 20% don't want more damage buttons but are fine with more damage buttons.
3) Combined with the ~80% who want more damage actions, this would make an overwhelming 97% that either want more damage buttons or don't mind more damage buttons.
X) The obvious conclusion via this interpretation would be to add more damage buttons to all Healer Jobs, since the amount opposed is an insignificantly small minority
However, this is wrong. The reality is:
1) 2-4% want less damage actions.
2) 18% more do not want more damage actions and some percentage of this, possibly a large one, would be upset with more damage actions. Specifically and explicitly: They are not fine with more damage abilities added to all Healers.
(Because "more attacking actions" was an option, we know that people that DO want more gave that answer, meaning those who did not do not want more attacking actions.)
X) This substantially changes the equation since we cannot claim 97% either want or would accept more damage actions. We can only claim with certainty that 80% would want or accept more damage actions, and some number towards 20% would oppose and be upset. 1/5th or 20% is an entire order of magnitude greater than 1/50th or 2%. The implication here is that we should leave at least one Healer unchanged.
.
The nuance in the distinction I'm making and what I'm finding fault with in your post is the difference between 1/50th and 1/5th, which is hardly a minor quibble since the first would suggest giving all healers more damage actions and shrugging off the upset people leaving the game while the latter is sufficient to justify not changing one Healer.
