I never got fully into the last 2 seasons, the mechanics were boring, the battlepass was bad, got my character to level 66 season 1 and 76 season 2 and got really bored.
This season the battlepass is nice, the pet is actually fun, since most pets in the game are just damage fodder, its nice to have a pet that actually does damage.
The Trap dungeons can get reptitive, but so can regular dungeons, at least you get extra goodies from the new dungeons.
I don’t understand all the hate for this season, my only guess is that people played a lot of the last 2 seasons and just got bored of D4 in general and need something like an expansion rather than a new season
