Have to disagree there that it would only be an improvement.
Fairy placement offers a unique advantage during light party/ pair/ spread mechanics that you wouldn't have if all heals were centered on the SCH. Things like placing Seraph mid during arrows on p2s, FoF on p3s and CC on p4s is so much better than other tools, same for light party splits on p5s.

The only reason you have to place your fairy is because skills are tied to it. If you don't you will either miss some players, or the use will be delayed because of movement (that will also miss some players). Placing a fairy is more like circumventing a flaw than a great feature in itself. I myself ran into situations that the fairy was too far away, placed in the middle, that I wish it were right at my side to use some skills in emergencies.

You're virtually the only job with this uniqueness, other players already gather around close enough that there is no point for you to not do the same. You have to place your fairy to prevent it from move away from others and not miss your mark with your own set of skills. There is also no point of you standing too far from your party just to place your fairy in the middle of the others and heal/buff them from apart, cause you will not receive their buffs/mits/bubbles/heals. You will also have to move in anyway to use the rest of your kit that is not tied to the fairy. If you consider people gathered around a boss, and your fairy right at your side, you will probably reach everyone else around with fairy skills, no need for placement. If not, that is because your fairy moves around you with a (expected) delay and distance, staying a little bit off than you expected.

Again, fairy placement is only needed to avoid skills not reaching their desired targets because of how the pet works in itself. It is not a great thing, it is just a way to avoid problems the system in itself brings to the table. Since EW, I would rather have fairies to be instances, just like SMN lesser summons, with Seraph being the big "Bahamut of SCH" in some way. SE could bring variety to both Eos and Selene "instances", removing the nuisance that is managing pet placement.
