The 100 grind doesn't bother me because the incremental power increase from 95 to 100 is negligible. In D2 those points mattered far more. I can see the hate for the grind, but I just have no desire to hit 100 and there are no real in-game reasons to do it, so I don't sweat it. I have a serious problem with bosses being gated behind a power level that is not realistically obtainable in SSF and is only available through trading when the tools exist for them to make it still grindy, but ultimately available. The streamers and 15 hour a day players are always going to trivialize the content in the long run so I don't think it's a good idea to keep them as the ideal base to design towards.
