You and your theories again. If you actually played Dragonflight (a lot, at top ratings) you would never say such a bull**** lol. What is it with you, spitting totally random nonsense and lies without any single evidence? Literally every single time?
Shuffle had about the same attendance throughout the S1, then dropped drastically later, with literally zero impact on other brackets (don't make me waste time and destroy you with screenshots and real evidence again please...)
But other than that, I agree Solo queue is bad for TBC. Private servers with much smaller player base than retail have proved many times, that 3v3 and especially 5v5 bracket is very hard to "keep alive". And solo queue definitely does not help that. A lot of "random players" simply go and join solo queue, instead of taking the 5 minutes effort to find 2 other random team mates to get 10 games for points (or play for real) which makes the brackets active on daily basis.
You know what is funny? This is the exact principle as how bad for Onyxia server the cross-realm with Blackrock is. The same way solo queue will drain players from 3v3/5v5 - Blackrock will drain PvP players from Onyxia, butching the population there. Same logic - no effort, just free pew pew.
Irony, hm? ;)
In any case, despite you and Blakeatron pulling out random wannabe facts from your magical bag of lies and mysteries, spamming the forum and replying to every single message which goes against your personal agenda, you won't have any impact. Because if Warmane has already decided whether the solo queue will be implemented or not, it is done. But it would be funny to see you struggle against something what you don't like for a change.
