The problem is, the "already complaining about endgame repetition’’ bit from your original posting suggests it was rather early in the SWL life-cycle, possibly at a time when only the more ‘hardcore’ grinders were even E1 ready, while player numbers were still considerably padded by launch frenzy.
That would make the number effectively meaningless in terms of assessing how many retained players actually give ‘endgame stuff’ a shot.
It’s probably better to not post any numbers unless you can give enough context for a meaningful interpretation, and that wasn’t it - that was fodder for conspiracy theories.
