I am sleepy as hell at the moment, but by looking at your character, this looks like an improvement. I'd say run 50s untill you pump your gems to 50, and then try slowly to go higher. Of course, ancient weapon would be good, but that is not up to you, it's up to game whether it will drop it or not
And one more thing, if you are confident and are doing 50s with ease, you could swap out Vile Ward for Nemesis Bracers, it speeds up rifting quite a lot.
But that of course depends on your play style and what suits you the best
Diablo is grind fest that requires a lot of time invested:
- You need to farm up your gear
- You need to farm up materials and keys
- You need to level up gems you will use
- You need to level up gems that you will spend for Augments
This can eat up a lot of time, and having a group helps a lot (especially if you have someone with who you can talk on skype or teamspeak while doing it). It becomes tedious at some point. For me it's usualy arround paragon ~800 and when I finish Season Journey, because of other things in life that require attendance, like work and sleep and family time
Main problem with builds is that their sales line ("GR90+!" and so on) doesn't say that you most probably need to be 1000+ paragon, and to have entire ancient gear augmented, and to have gems that are 80+ level
You can check builds and items of people that achieved leaderboards by pressing in game Shift+L, and then selecting Hero Details. That might give you some idea on what works and what not.
For you, you need ancient weapons first, that should boost your damage for ~5 tiers of GR, and then to start working on toughness.
I can recommend Charge/Boulder toss build, which I am using now, and I'm having easy time in GR65 (without any augments and partialy ancient gear)
