There are two issues when Tournaments.
Either you make all the players the same rank - no level difference or boost. Which the old players hate as now they get to face newer players, and might just loose to bad draw luck.
Or Advantage Tournament, with the dinosaurs ran as they have been built. Fun for the older players who can now use they have not been able to touch in a while, as they have been focusing on the PVP team, or other such things. But dreaded by newer players who barely have level 20s
Yes, both have issues. But in order to make both sides happy, sometimes newer players are going to suffer and sometimes the older players that lose because of RNG to a new player.
And i doubt they are going anywhere, anytime soon. Realize, Rare, Epic, and Legendary are still used at least to the Aviary and Library. So seeing them at level 30 is not to uncommon for those higher level players. But for those who are still ‘new’ to this game, you never see them, so never realize they can still be a danger for a long time.
Enjoy what you can. If you don’t like the Tournaments, wait for the next one which will likely be different. And remember most importantly.
IT IS A GAME!
