I guess as new people join, some things bear worth repeating periodically…
Our responsibility to the game is balance at all levels of play. This is something many people forget/don’t seem to realize. The vast majority of the playerbase does not play at the level that concerns forum goers, and any concerns about build viability at SR9000 and Gladiator Crucible 3x clear times are effectively irrelevant to them.
This is also why some things that certain users consider to be “big issues” or “desperately in need of redesign” are often not actually all that problematic because for the average player they are not only viable, but they also enable alternatives to min-maxed playstyles.
Obviously, the prospect of a game balanced at all levels of play is a very complex one. One could argue that it’s not even feasible with all of the moving parts intertwining in an ARPG, but it is one worth striving for nonetheless.
When it comes to balancing build performance, we have our own standards of what we believe is healthy for the overall game, even if those standards don’t align with what some builds consider “crap” or “fine”. When we observe outliers, we look into bringing them back into the middle.
Now that is going to happen whether the community works with us or not, which is why I like to remind builders that you really have two options: work with us to improve the game’s balance or accept whatever changes come your way.
Some have accepted (and benefited from) this over the years, while others feel that they need to treat us like some enemy to resist. Don’t forget that the devs have really high -%RR against Nerf Resist. 
At the end of the day, we all want the same things…more viable builds and more ways to enjoy the game. This can only be achieved by finding a happy middle-ground between the overachievers and the underachievers.
