They are calculated perfectly fine, but it's not a linear curve, it's rather logarithmic.

Yes, and that's logical, you need some survivability aside from your dodge, if you could reach 100% dodge, that would make you simply invincible, so EVERY player would just do that!

Nodes are thus a nice boost if you have a low dodge score on your gear but don't do much if you already have a high dodge.

its working fine, but if u get hitted u need plan B, it means high ALL res or u may try to combine high dodge chance with tenet points passive - this combination should work fine

I dont think that's working fine

how does anyone justify investing 20ish nodes to gain multiple +15%, +20%, dodge passives to net you a total of +5% dosge chance?
that's makes zero sense.

Especially when I can take a literally 3 praetorian nodes and have 80% block with no shield, or have 95% block and put a shield on.

it prevents from reaching 100% dodge chance, u have some value and every additional per cent is not additive per cent, but its per cent from percent, then its adding

in block chance u have additions system when 10%+10 =20% and u can reach 100%, but with block it is possible, cause dmg received depends on block efficiency, similar algorithm like dodge ,u have blok efficiency which also prevents block efficiencty to reach value of 100% and bve immortal
