I am familiar with the loud cry of "the challenge has been lost!" here and elsewhere. Maybe so? I feel that's a subjective call. And if anyone's feeling tedium with the game, that's really more about them than the game; maybe they've played it too much (I know I have and the second I feel that tedium I log off).
I could be wrong, but I think the original devs took out some of the End-drain nuke effects, and people do very much so still carefully consider the builds, at least as much if not morseso than they once did (I'm guessing we're a concentrated group of hardcore players more likely to do so). I mean, why do speed runs if you're not looking to grab the merits faster to trying to buy extra-big things for your build? I don't think speed runs aret a sign of tedium, just over exposure (and new content is never going to come out fast enough to suit everyone).
Ultimately it still comes down to if you're bored or don't like HC's changes, you don't have to play here; I know that's not a great option, since people obviously do want to play here, but sometimes things just go that way, it's like thinking "I wanted to like the last movie I saw but..."
