so let's say my bvc has 40 efrw from increase speed and 125 frw from items, it would have:
(150*125)/(150+125) + 40 = 108 efrw?
that sounds kinda ridiculous
that would be the same speed as 386 frw from gear without any skills
Didnt verify your calcs, but yeah its crazy how effective it is
From the top of my mind, 300frw = 100efrw
But if you have 50 efrw from skills, then to obtain the same total speed, you only need 50 efrw from items, which is 75frw
300frw from items = same speed (100efrw) as 75frw from items + 50efrw from skills
This is why people aim for certain breakpoints of frw (which are more and more distant) around a big maximum of 150frw, cuz above that the diminishing returns hit hard.
But yeah…. You always get the same bonus efrw from gear, no matter if you already have some efrw from skills or not.
