The problem is your “threshold” is at Max and you expect it to be overcomed
Now sure, that’s what the game “offers” so in a D3/Pokemon fashion “gotta catch 'em all”, but it shouldn’t be like that
The more realistic look at it would be like - if doing decently well and not playing bad and have decent but not perfect gear it should feel like normal fight progression against T35 or so, so it can be selectively slowed down against T50 so it feels like an “have to be careful and effort is required” but not entirely stopped
And then anything else above T50 is a bonus (not an expectation)
Why should there be builds that clear T100, have you thought about that one as well ?, how would a “leaderboard” look like if people can clear T100 ?, what would differ them one from another (clear speed ?, timer ?), how about make a proper game that it’s almost impossible to get to T100 and the “best of the best” get stopped at T85 or so ?
Wouldn’t that kind of leaderboard work ?.. I mean just remember that at T50 you already have a lvl100 character so if not competing for a “leader spot” you’re practically done (in 1, 1.5, 2 months ?, whatever), and can start another character from scratch
That’s the thing, by “pretending” T100 is reachable, Blizz really does a really bad disservice to players… In general all builds should start struggling before T50 in one way or another so there’s a bit of “slowdown” at lvl100 (i.e. T50) back to normalcy of progress and respect of difficulty of progression
The “pushing above T50” is something that should be intended for those that want to compete (not for everyone), and as such shouldn’t be expected to be beaten
Think of it as a long jump competition… The measuring “tape” goes to 10 meters, but noone can jump 10 meters (if I remember correctly somewhere around 8.8m is the WR)
THAT’s how the difficulty progression should also work where DISTANCE ITSELF is the mere indicator of who did what (and how much), and sure, there could be some “roughting out” the edges in terms of gear the more you push above T50, but it should never be a thing where the smaller and less and less frequent “fine tune upgrades” are sufficient enough to make it expected to clear a T100
