When I came back to D2 some 2 years ago I began to run LK run big time. I had played the game excessively before was at somethin like grail -8, so runewords were a main focus initially. Similar to what
@GalaXyHaXz said -- it was done in no time. Infinity, Enigma, Griefs, Fortitudes Faith, Dreams... Made them all of that within a couple of months.
However, I don't think that's a bad thing. First of all, it still requires dedication to do these pretty boring runs for many, many hours. IIRC farming Enigma in LK based on 25s runs or so takes somewhere around 50 hours. That is something, it's not nothing. Also I don't think HRs should have been that rare in the first place. On bnet, this lead to mass duping (everyone was using them anyway) and forum wealth determining things. On SP, yes it took years to self-farm a high-end runeword. Looking at it that way, "easier" seems to be just "better" to me. I couldn't care less about RWs anyway, the truly amazing items are those really rare uniques which I still haven't all found, as well as those "individual" items (rares, craft) that exist only once.
So in short, to be honest, I think it's good that the HR drops increased, and I don't think the really rare S&Us drop too often at all. For me it doesn't take away any sense of accomplishment at all, and there's always something else to do if you want to continue playing.
