well I find trials are a bit easier now... there have been a few nice additions to the mix that help, like Weapon and Sheild of the Ancients.
I have never played a Psi, so i cant offer any tips in that regard, but i did struggle for a very long time with a 51 scout. After patch i found a few trials were a bit easier, ones i used to have a real hard time with (Defensive measures, and Carnage) were now passable. Luck of course was also a huge factor... I managed to actually complete them and get my rein
it certainly cant hurt to come back and try them again
Maybe put up another post after, let us know how it went, and if you notice any changes??
