@maze As the game is based on ADaD, I believe even some magical skills in Fractured might have "dodge" saves - called reflex saves in ADaD. If I take NWN2 as example, many spells have reflex save. I love the idea that spell can either affect you mind / thinking (willpower save), body integrity and resistance to body disabling effects (fortify save) and that you can even completely dodge spell effect (if it´s dodgeable - mostly direct damage dealing spells - projectiles like various arrows ( flame arrow, posion arrow or spells that will test movement coordination like grease ).
However in Fractured you can "skilldodge" just like you can "skillshot", so you´re probably right that evasion might be subpar - as long as player is skilled, Evasion might not play such big role.
In melee situation its imo similar - dude with supreme evasion might evade MOST basic attacks (so far so good, because you can also evade crits), but many superdamaging abilities in game have "always hit" property, so you evade low dmg autoattacks, but eat nukes 
Whats more - heavier armour further reduces evasion, so evasion seems like fine bonus, but nothing I´d max unless going ranged character.
Just for illustration - i went 6 DEX and rather raised my other defences. Attack speed can surely be increased in more ways and If i need some evasion, there are other ways - because if charisma gives such nice bonuses, why go DEX which only slightly increases attack speed.
