People who use their buffs together actively do more DPS. I...would think that obvious, but that's what I mean by favors.
That change, btw, seemed targeted at the midcore. The "lowest common denominator" players don't line buffs up even now. What it did was make the midcore more capable of consistent buff alignment, and made it easier for the hardcore to to line up buffs - contrary to your statement, they weren't all coordinated in ShB simply because there were so many different CDs - 45 sec, 90 sec, 60 sec, etc - that there was just no way to get them to play nice together. High end players either picked all Jobs that had compatible CDs, or they just picked which were most beneficial to line up. The EW change streamlined this for those players, thus making things easier for them. Note that this is another definition of "favors/benefits".
So it was made for the midcore, and it helped the midcore and the hardcore. Casual/"lowest common denominator" players weren't then, and still aren't now, lining up buffs and keeping buff uptime, etc, so the change wasn't made for them, didn't help them, and if anything, has made their performance worse by relative comparison since everyone else is now doing it, and doing it better, than they were before, growing the gap.
Maybe, I just don't think it's really valid.
I think the system is what it always has been - one of each and one wildcard slot to fill as the party sees fit.

EDIT: Bah, daily limit. Well, will just have to make due with this.
No, it's what I said - for the midcore. Casuals weren't anywhere close to doing it, while midcore players were trying but failing. The change was made for the latter, not the former, and benefited the latter, along with the hardcores by making the square peg they were trying to fit into a round hole into a round peg so it actually fit.
But I do agree it was bad execution, and it was apparent almost immediately it wasn't working as intended, yet they stuck with it anyway, even though it clearly didn't help the casual low end, annoyed the high end, and while it helped the midcore "feel better", since encounters were then balanced around the expectation of that level of damage, things didn't really change for them - before they weren't aligning buffs and were clearing content with difficulty, now they're aligning buffs and clearing content with difficulty.
So it was a failure all around and......and deja vu. Hm. I feel like we've had this conversation before. And I don't mean this topic. I mean, that I've typed that EXACT conversation before. Weird.
