The problem with some of your questions is that the numbers all change based on your current gear etc. My personal recommendation for ancient/non ancient is that when it comes to your DPS pieces the right stats are more important that if it’s ancient or not. I have a non ancient flavor of time this season that when I test it on D3planner is actually more DPS than my ancient WITH a level 105 augment. I still went with the ancient only because it has 22,000LOH which i really need the LOH and it allowed me to swap to critical on my law.
I would also highly recommend looking for a new shield asap. It looks to me like the damage boost on your shield is an old max value? It says 300% on your profile, that’s the current shields minimum value these days. I also don’t see a unity on your profile, that makes a HUGE difference.
If you check out my profile it will give you a good idea of what to be shooting for. Currently it’s displaying my tankier gear set for speed farming 100-105 GR’s to level gems. My full blown fire dps that I completed a 118 GR seasonal on last night swaps my cube stone gauntlets for aguila and equips a cindercoat for the fire damage. I also swap my iceclimbers to illusionary for the mobility. I’ve still been running the steed, though i’m tempted to try a different skill to see if i can find something that helps me more.
