i don't know the individual player so i couldn't say.
and yes the stats do matter it's why we have bis. do i know it? no but i also don't play for bis.
if you see a player in all tome gear or all raid gear they are weaker then someone who finds the best gear (secondary stats)
could they get tired of it? of course. does that mean they will? no
people who think a like normally play together so if someone doesn't like the progression there is a good chance thier friends will too. (not saying you don't have a point) but just because you know a few people who don't like how progression is doesn't make all of the players.
