Sunsetting killed the game for me too, I wasn't able to replace ever piece of gear to keep my stat split correct and there were still entire element and weapon types missing entirely a year after it went into effect. I took a break, then a longer break, then never went back because I felt like I missed too much.

I heard they fully un-sunset everything they had sunset, but at this point I have zero desire to play the game anymore. This is after having played thousands of hours and having D2 as the only game I played for much of that time. As a 50/50 PVE and PVP player, the slow death of PVP and the removal of half the raids kills the game for me.
