I haven't played Diablo III in a while, but I jumped back into Season 16 when it started a week ago.
Normally, I stop playing Diablo after I finish the first four Season chapters and get the full 6-piece set. Usually Torment 6 or Greater Rift 20 or so. This time I've decided to make an attempt at getting into the Diablo III elder game. Primal legendaries, ancient primals, Torment 13 etc.
I'm basically following an online guide to the Hammerdin build, and it's going pretty well. I'm in Season chapter V. I still need to find a proper weapon and shield for the build, but most of my other pieces are decent. Though I cannot roll a socket on my amulet to save my life.
It's interesting because usually I don't "farm" in Diablo. I play on difficulties close to my gear level, pushing to finish the chapter requirements. Enemies seem to take a while to kill, but also take a while to kill me. This time around I'm farming T6. Everything dies super-fast, and I can finish a rift in five minutes or so. But everything also does a lot of damage, and death can happen very quickly. It feels very different from the Diablo III I normally play.
Season 16 is the Season of Royal Grandeur. There's a universal buff which mimics the effects of the Ring of Royal Grandeur, allowing you to get set bonuses with one less set piece (minimum of two pieces). It's an interesting twist. I'm currently running five pieces of the Seeker of the Light set (so I get the 6-piece set bonus) and two pieces of the Blackthorne set for the 2- and 3-piece set bonus.
Playing Diablo III this way is an interesting experience. Probably what most serious Diablo players are used to, though.
