Psi nerfs I can agree with to a certain extent. I think that Force Field should be nerfed even more, by only casting a sinlge tile under base conditions and you should get additional ones depending on your Psychokinesis skill.
Crit Power nerf is also something I can live with.
However, I'm really devastated by the nerfs my temporal sniper build have to suffer. It was so perfect. If I interpret the changes correctly, then Rapid Reloader doesn't lower the AP cost at all, it only has a small 25% chance to provide aditional AP from time to time, and even then the bonus will be a random amount between 16 and 20 (with a Spearhead). This makes it completely unreliable and brings more RNG - something my build efficently ruled out in favor of maximum efficency. Now I cannot count ahead with my AP and also even if I receive the bonus, thanks to the Spearhead nerf, I can't shoot 3 times even with max bonus from RR and Temporal Contraction.
The main point in making hybrids was to utilize the synergies between different abilities - that part was the main reason I though so highly about this game's design. Now that's gone. Especially with what happened to the Temporal school. Now there's no synergy anymore, just skills on their own. I can't help but feel that this update is from some bootleg alpha stage.
Regarding Temporal Contraction... that nerf is the death sentence for my build. It's made around using that spell with the fully specialized Acceleration feat, so being buffed every 4th round for a whooping 72 AP 3 out of 4 turns. I honestly thought that with Expedition, this spell being used with the Rapid Spearhead's AP cost of 24 is intentional by the devs promoting psi hybrid snipers. It's not unintentional fortunate circumstances, they acutally thought it out like this. My build is tailored to use this ability not once per battle, but for at least 3 times, enjoying it's effects for 9 turns out of 11. It is why I have increased Will and Intelligence too and took up 3 psi feats. This nerf brokes that to pieces as if you use it once, you better finish the battle within 3 turns (if you wasted a feat slot for Acceleration) because if any enemy is still left standing afterwards, you'll be helpless and die.
This makes Contraction to be used when the fight is nearing it's end. When it'll be completely pointless. The point of this spell is to use it FIRST ROUND when there's many enemies to clear, so you can take as much down as possible before they'll be able to really utilize their advantage in numbers. So after it wears off, you'll be left with less, making it easier to deal with your base AP. Now the fear of it backfiring on you will make most people use it when they can estimate the fight's end within 3 rounds, meaning they already dealt with the enemy's main force. This makes Temporal Contraction utterly useless against crowds - the occasion when you need it the most.
I only used Increment and Contraction (not even force field as it seemed broken and basically cheating in it's former state), so I'm fine with the spell slot restriction too. This update was meant to favor psi hbrids as they have more divided stats and skills compared to pure psi users. But with nerfing Contraction like this, there won't be any point in making psi hybrid builds, I just go pure firearm. Definetly doesn't worth to use Temporal (let alone tailor my build around it) and loose 25%HP for psi empathy, waste all that stat points, all those skill points and 3 feats slots to have a broken build that's specialty is self-pwning when you can invest all that and go pure firearm user and specialize in it completely without suffering the compromises you made for being hybrid.
The Temporal nerf doesn't propagates hybrids, it makes them impossible to use. It benefits complete psi-less builds, thus resulting in the exact opposite of what it hoped to accomplish.
I just hope that update won't be forced on everyone, the devs should leave it to the players which version they want to play depending on if they would like to play hybrids (then go for the previous version) or pure psi users / psi-less builds (go with the new update).
