Very similar to what chatgpt said, thanks!
So the conclusion is that it wouldnt be worth to spend more than 10 hard points into increased speed passive skill because it barely does anything at some point
No it’s the complete opposite of what chatGPT said.
There is no diminishing return to skill EFRW.
Only diminishing returns from FRW (from gear).
And they are independent from each other.
Let’s say you have 37% EFRW from Increase Speed.
37 * 0.06 = 2.22 yd/s bonus speed
Let’s say you have 105% FRW from gear.
(150 * 105) / (150 + 105) = 61
61 * 0.06 = 3.66 yd/s bonus speed
If you have only the bonus from Increase speed you get to
9 + 2.22 = 11.22 yd/s run speed
If you have only the bonus from gear you get to
9 + 3.66 = 12.66 yd/s run speed
If you have both at the same time, none of these 2 bonuses are diminished. You get to
9 + 2.22 + 3.66 = 14.88 yd/s
What is bad is getting too much FRW from gear. The higher you have, the less effective the next few % bonus will be. But skill bonus is always 100% effective, and it’s not negatively affecting your bonus from gear.
Now… the question is: is moving faster on a WW barb really good?
The answer is far from simple.
If I had to resume it in a single word I would say… no.
I may come back later with more explanation of “why”, but I don’t have time right now.
