Ehm, what’s your point? Isn’t that what’s being done already? Uh?!?! o.O
I don’t see the value in posting the worst times (also by who? the build poster? I think some comment their different times, some don’t; by other people trying the build? then it’s on those people to post them, and they already have the space to do so). A build poster can’t account for every single person’s different skill, but those people trying the build can account for their own skill and conclude that, if X skilled player got let’s say 4 minutes in their run, then someone trying out the build will get 4 minutes + an amount according to their skill level. Besides, from a balance-wise perspective, I think it’s just way easier to account for all the variables when looking at the high end of anything, which has a ceiling (what the minmax community strive for), than looking at the low end, because it’s just never ending; do we buff a build because Timmy insists on putting only 1 point in Shaman and maxing Savagery? No we don’t.
Again, I don’t know what’s the point here. Yes, we all can look at, for example, Steam’s achievements and see that barely 6.8% of the people have completed the base game on Ultimate (without even accounting for HC, mind you). Afaik, SR30-31 is the agreed upon run to maximize the loot drop per time invested, since higher shards won’t really mean better loot, but this doesn’t mean that builds can’t go higher. I think most minmaxed builds can do higher (and if after minmaxing it’s still underperforming, it can be shared so more people can either help minmaxing further or evaluate an actual problem that might need the devs attention). Again, look my previous point about Timmy’s character building.
I think there’s a bit of a misunderstanding; the fact that builds are balanced around the high end of players/skill/times/etc., doesn’t mean that Crate won’t consider new or lower skill players when balancing stuff; if anything, the leveling process is way easier now than a couple years ago (in a good way I mean), farming gear has also been buffed with MIs always dropping from bosses and better affinity between affixes and their gear, even the recent addition of RR to some of the masteries open up more possibilities for homebrew builds without requiring specific gear.
In the end, imo, it just comes down to knowing your own skill level; for example, I know that if I see some of the people here posting a 4 minute run on a build, I will most likely get around 6:30 to 7:00, maybe adapt some more stuff since I play on HC only, etc. I would end up with a homebrew version that will most likely have higher times than the minmaxed version but it would feel better for my personal playstyle. Should my slower, homebrew version, be taken into account for balancing the game? I don’t think so, since I’m taking the informed decision of, for example, sacrificing some damage for defense or something similar.
