I think Premeditation cooldown reduction is the best 2 points you can spend as psi. I tried LoC cooldown reduction but didn't much like it since I rarely had fights go long enough to use it twice even with the reduction. SI Psychosis specializes in SURPRISE YOU'RE DEAD and that doesn't really lend itself to needing cooldown reduction; you just wait for your psi to regen and by the time you're topped off, most of your cooldown are good to go, too.

I would say put your first two points in Premeditation cooldown reduction and see if your playstyle doesn't show you where you need to take it. You'll be level 17 by the time you have to think about where else points should go, and I'd bet you'll have figured out a bunch of things regarding how you play the game.
Once again, many thanks for your insights. Premeditation CD does seem like the biggest bang for your buck investment by a large margin. The character is 16 now, just took the first point. She's been burning, shattering, frying, and terrifying everything in her path with reckless abandon. I'm leaning towards the SI health threshold buffer for the future, simply because I feel it will allow for a slightly more aggressive and dynamic combat style. The number of resources and tactics that a psy character has at its disposal is insane and I find myself wanting to put as many of them to good use as possible, as often as possible. My biggest fear now is how will I ever go back to playing non-psy in the future now that I've tasted such power?
Thoughts on shield emitters? What's ideal for a psy char? My Tin Can just stuck with the highest quality efficient low-high he could manage crafting for early/mid game and then transitioned to an efficient low quality single low once he was in Super Steel. For this psy girl wearing far less armor and having far more mobility and utility I'm not sure which of the shield flavors is the best option. I'm leaning towards an amped low-low (or med-med perhaps?) because the scariest opponents are generally xbow users. Just not familiar enough yet with crafting SEs to know what's best.
