Now we simply declare that pool openly, while still relying on the very granular metrics (behind the scenes) to give you guys the best matches we can.
Getting tied up in the specific number doesn't seem to give any positives, except in the highest points of the ladder (which we've addressed).
I think the elo numbers reflect 'you are doing something' in ranked play, e.g. right after I've won a match, my elo raised, this shows I am climbing up towards the top. In other words, a continuously changing elo number reflected players' effort as well as their skill level.
But only with the 'Tier' in the coming new league system, some may feel like they are fighting for nothing significant enough other then 'league points'. As a player, I really consider that a visible elo number reflects many things instead of solely the 'skill level'. I will feel much more comfortable if elo ranking is kept visible.
