Ok its near the end of the month and played a new expansion on a new account. The time it seems to q is becoming longer from rank 50 meaning less players coming into the game. This over the month not just a day on Asia/NA/EU servers. The timer from each expansion from April 2019 at Rank 50 to 25 seems to have got longer. April last year seemed very active with an average time of 10 to 45 seconds q time, with each new expansion the timer has got longer by 15 seconds. The present timer for this month at present is 30 to 2 minutes. This is at different times night or day , with night being more longer up 4 minutes or longer or not even getting a game.
I have rolled many accounts and rank up each expansion from Rank 50 upwards free to play. The timer on the q I judge as an indicator on the health of the game from new player experience. The latest expansion and the new Pve content release seems not to have an impact on numbers maybe fact the other way. This may not be the best way you may say but playing the game across many accounts / servers has lead me to think that the state of the game maybe coming to a end if the present trend continues over the next year.
I follow the MAU numbers and stats from each quarter and run scenario on the state of the game and playing the game also.
