Ok, so, first, if you want to push higher GRs at some point, you should go read Free’s guide (carefully), because that has everything you need.
That said, for speeds, there are some things you may want to change…
Biggest issue: it looks like you are using a legacy Lamentation! These lack the damage bonus that the newer ones have. Even the worst imaginable new Lamentation will be far better than the old one you are wearing. So, time to spend some blood shards, or upgrade rare mighty belts in the cube!
Next, if you are killing the Rift Guardian fast (less than 15-20 seconds), then you don’t need Stricken (you definitely should not need it for T16s. Probably not for 90’s, and maybe for 100s). I usually use Gogok just to help out with cooldowns, or if you want some extra damage you could use Trapped.
For speeds, you also probably don’t need Ancient Spear… although for “high speeds”, where the mobs don’t die right away, you can still use it. Same goes for Stomp- you definitely don’t need this for T16s, and you shouldn’t need BoM either. Same goes for GRs up to about 80. Above that, Stomp and BoM may be handy.
I’ll mention the Fury issue again- easiest solution is to swap to WW: Wind Shear, for Fury generation, BR: Swords to Ploughshares for Healing, and switch Weapons Master to Rampage (or, for T16s and lower GRs, you can use Pound of Flesh for extra speed). Note that while it may look as though Weapons Master is better than Wind Shear for Fury generation, WM actually has its generated Fury reduced by the proc coefficient of the attacking skill. Meaning that for WW (coefficient 20%), you only get 0.4 Fury per hit, much worse than the 1.0 you get from Wind Shear.
For T16s and lower GRs, you can also try swapping your Mortick’s for Nemesis Bracers. These help you clear the rift faster by spawning extra elites to kill when you click a pylon. For 90s and 100s, you may want to hang on to the Morticks for toughness, since you are not high paragon.
Anyway, for reference, here is my speed setup, that I use for T16s and GRs up to around 90: Rage#13139 - Community - Diablo III (diablo3.com)
You may want to give that a try, and if you find it too glassy, just swap Nemesis to Mortick’s.
We should also check in with Chris. He runs more speeds than anybody else around here.
@chris#11418 , advice requested…
Hope that helps. Again, biggest thing to fix is to get a new Lamentation!
