Of course, there are those of us that have certain ... problems, making optimal gameplay not something that can be commonly done. Whether it's due to hands not pressing the buttons your mind is telling it to, or a complete inability to focus on more than one or two things at a time. I, for instance, cannot keep track of cooldowns/buffs/DoTs/AoEs to move out of the way of, as well as doing perfect rotations without messing something up regardless of how much practice is put into it due to some limitations my brain can process at the same time. I've played Bard, and only Bard, since 2.1 and I'm only an average player that can play to the absolute best every once in a while.

But I know who I am, and I stay out of content that's too much for me. No EX Primals or Alexander for a while, until Echo comes into play.
