Is there a guide out with info on how to do rifts? Info like if its faster to get Rift Guardian to appear by killing only yellow mobs or only yellow and blue or if big groups of whites are good too? I have no idea if it is faster skipping most enemies or not given that they all add to the progress bar to some degree yet whites drop no % bar orbs.
I find it funny that there are character builds for speed rifting yet I can't find any info on what speed rifting is or how its done like how it differs from normal rifting other than just a different build.
I can't say I have a definitive answer as I haven't really analyzed my speed/timing carefully.
I am running punish/inoker sader and easily clearing t10
My strategy is to ride my pony around until I find a blue/yellow or a shrine (I use nemesis bracers). Generally by the time I've found a champ I have a nice supply of trash mobs around me. While I'm killing the elite/champ, the trash tends to die. Then I move on. Seems to go pretty quickly, clearing in 4-6 minutes depending on the rift.
My barb on non-season I have a build a WW build that allows me to move at 250% move speed. Which allows me to clear a rift on average in 2 minutes. I know wizards could keep up with me and monks. Demon hunters seem to be able to now as well.
Sadly this season I'm playing leapquake. And I move at a snails pace lol it's incredibly frustrating. And it's hard to tell if leap actually goes faster than 25% move speed and add to the fact that leap is frustrating to use as a moving tool considering half the time I just leap into the same spot. The clipping in this game is a bit annoying. Sorry my barb shouting and grunting all the freaking time is more annoying.
edit: to answer the question speed rifting is well down to how fast you move. Unless you can't 1-2 shot mobs. In that case simply ask yourself if doing a rift on T8 in 2 minutes compared to T10 in 5 minutes. With leg drop rate being 295% and 461% so not even double the drop rate. Yet it takes more than double the time.
