Ranged DPS role is about to be excluded from all content

Yeah, agreed. e.g. For MCH, wildfire comes up a fraction of a second before one of the eyes goes off in E2S. Depending on your sks, you might have to delay it. This kind of stuff is all over the game. Not to mention the extra distance you frequently have to run to accommodate the rest of your group for mechanics (E1S, E3S have lots of good examples). There's a lot of moving ahead of time and then getting back fast for AoE heals, more so than the healers/casters at times.

At the end of the day they balance around the ~60% mark for player efficiency (barring deaths) for this reason (with intentional creeping gear inflation pushing that to the 40% mark).

This entire discussion comes down to psychology:
Nobody likes the creeping realization they have to chug meth to do what a half-sleeping person can on a different class.. at least not without bringing utility that makes a visible difference to them (like ver-raise! the champion of learning parties!)
