Ye. Lets say you are that average guy on LB. Lets say you are able to do 117 with enough pushing.
So I imported your char in d3planner. RIght now you have 23,524 dex.
At lvl 5000 Paragon you would have more dex from Paragon and you would be able to augment gear with lvl 130 augments. Your legendary gems would be higher lvl also.
Now did Blizzard scale everything up??? I have no idea.
If we only scale Paragon up you jump to 36,169 Dex. That is 36,169/23,524 = 1.537 multiplier or ~2.7 more GRs.
If we add lvl 130 Augments on top of more Paragons you jump to 38,084 dex. 38,084 / 23,524 = 1.61 multiplier or ~3 more GRs
Now we assume that you lvled up Legendary gems also to lvl 130? That would be 2.6% more damage from Bane of Traped and 3.4% more damage or around 6% more damage combined.
1.61*1.06=1.7
So it is realistic that you would gain 1.7x more damage when you are at Paragon 5000 and if you don’t change any gear.
1.7 multiplier is worth around 3.38 GRs.
That would bring your 116, almost 117 to GR 120. With current items. That means UE needs +10 GR to bring player of your skill and gear to GR lvl 130.
As you can see we are speaking only about damage multipliers here and we are not discussing Damage Reduction at all. I am not going to cover that here.
How to get 10GR with UE? We need 4.8 Multiplier.
UE6 is giving 350% increased damage for every point of Discipline you have.
We run with 86 discipline. That means UE6 is giving us 30100% that is 1+ 301 = 302 multiplier. To get 10GR more we need 302*4.8=1449.6 multiplier. Lets round that to 1449. So only from UE we would need to get 1448 multiplier.
You get that like this: 144800%/86= 1683%. Lets round that to 1700%
So they would have to change UE6 from 350% to 1700% to give us ~10GRs.
