ntelligence makes you better at hacking, shopping, and all crafting skills
And nothing other than hacking really matters unless you're playing the game through mass crafting.
I just don't think it's a fair apples-to-apples to compare Strength or Perception or Agility or even Dexterity to Constitution, Will, and Intelligence, which are fundamentally more helpful to the character.
Agility means stealth, which provides in-game benefits as much as persuasion and intimidation. Dexterity generally means all thieves' skills: picking locks, pickpocketing and, finally, traps, which, unlike the previous two, are not optional at all. One and only truly irreplaceable skill.
High Perception means guns. And guns are the most versatile offensive skill in the game, including blasters, rifles and, in general, almost any means of destruction. It also allows you to quickly notice any lovers of stabbing a knife in the back. Or a tail. If you've met a crawler, you know what I mean.
A High (6+) Constitution is a requirement for Fast Metabolism feat. For any psionicist, the ability to increase the effect of the Psi-Booster to 100 (120 with specialization) psi is a gift from heaven. Not that it is necessary (I always needed stats elsewhere, so I never took it), but definitely useful. There is also Hemopsychosis - just a godsend for any Psychosis-type Psion, especially relevant after the patch. And then there are Survival Instincts, which increase an already decent psychotic critical strike chance by another 30%. And these are just feats that are directly useful for a psionicist, I do not even mention the possibilities that the Constitution opens up for simple survival.
Strength, again, can be directly applied to enhance Psychokinetic abilities. And also our carrying capacity depends on it.
To summarize - there are somewhere zero basic stats that the Styg has made useless. Almost every stat can be useful for this or that psi-build. But since the Intelligence has become not only "useful" but obligatory, I believe that its usefulness should be increased.
P.S. I will expand my position a little to make it clearer. Previously, 6 intelligence was enough for psi-wizards (requirement for Premeditation Feat). This is a good, convenient number, which allowed us to both reach 10 Will and leave enough to increase other stats to the optimal level. Usually it was even increased to 7, since 9 is the highest Intelligence check in the dialogue. One 10, three 3 and three 7 are the usual scheme of scattering stats for the minimaxer. +8 stats for leveling up and feats went exclusively to Will.
Now I need to remove five points from Will and send them to Intellect. Just like that, without any tangible benefit to the build. I would understand if most builds had to raise two stats beyond 10, but no. Even a seasoned crafter can live with a 7 in intelligence. Psion, if he wants to act to the fullest, cannot. There is not even some kind of contradiction where to invest points, in Will or Intellect - there is no such increase in power that would justify the reduction of the arsenal to several basic abilities.
Seriously, Styg seems to be collecting tribute from the Psionics with Ability Points.
