I kind of disagree. I think ladders are this Groundhog's Day like recreation of your first time playing through the game. Desperately trying to grasp at the fun and excitement we all had when the game was new and there were legendaries to be had. In their current form, they are a failure. Adding 11 legendaries with mostly uninteresting effects--the Crusader shield is probably the only one that is even remotely build changing--is a complete letdown at this point for those of us who have already put hundreds of hours into the expansion. Maybe that is what you mean by seasons not being for people who never stopped playing, but I stopped playing with any regularity a few months ago and I don't feel like I want to come back for seasons at this juncture at all.
For me, the initial appeal of Seasons was to start over, rebuild my fortune of legendaries from scratch in order to get a chance at some exciting new legendaries that, at the end of the season, I could bring over onto my main characters who could then REALLY crush some shit. If they don't add 20-30+ more legendaries to each Season, I don't really have any interest in doing them. I CERTAINLY don't have any interest if the legendaries that they DO come up with are like the ones they've put out so far; because, by and large, they won't make playing my classes more fun, nor will they make playing my classes more powerful.
They need to just make a ton of crazy, OP shit and even if the drop rates are miniscule, we can at least have that carrot in front of us. How do they intend on us to progress past GRift level 35-40?
