I'm not going to claim I know what most Beyond players think about the league. I do know that HC players tend to be more...well, hardcore about things and thus may be more apt to like the challenge of Beyond, and/or look forward to getting to a point where their dps can match portal mobs.
That being said, I think it's telling that there's very little discussion about Beyond on reddit. I remember many folks posting pics of various Rogue Exiles they ran into or crazy Invasion bosses, or even Nemesis mobs. Before the patch came out many people were excited by the names of the various portal bosses, which were revealed beforehand. Yet today...most of the talk is about new uniques, maps, and various bugs.
One thing that struck me about the build up to this patch was the lack of any gameplay videos about the leagues. GGG released a video showing how the player housing works, but no rampage or beyond stuff was played through. I thought that was pretty weird, given all the stuff they showed for previous patches. I know they tested this league, I know there was a beta, etc...but I wonder what the feedback was like. Ultimately I think the league can be fixed with a couple changes (increase drops, decrease life regen/life pools on portal mobs) but first impressions are important...and they seem to have whiffed it.
Again, I'm liking Beyond outside of the drop rates. But I'm probably in the minority within this thread.
