I don't even want to call them diminishing; they're all-but-unnoticeable.

From 90 PIE to 202 PIE I observed no changes- I don't have a parser, but I imagine there would be -something- apparent in that kind of point difference.

Taking INT from 17-90ish did raise my damage on Dodore's Minions, but after ~100 it just seems so minimal, if it's even there.

Even if >90 PIE does make a difference though, you will always land more than enough to survive with 90, and the extra points do the most good in VIT. Yeah, you can get some extra damage from INT, but adding 100 INT will boost like 10-15% damage...which only really helps your speed, whereas VIT lets you live forever!

This is my biggest issue with the game right now. Between party grinding, camps, class uniqueness, endgame/dungeons, equipment/HQs giving same stats-- the stats of a character/class having no consequence (or benefit) just drives me up the wall.

Even if they added all kinds of endgame dungeons/events/areas in the very next patch, playing through them with 174 VIT on a mage just ruins the appeal for me.
