Fire/psi is still fine. It's not as highly damaging as Fire/Fire, but you are better at surviving than fire/fire and have great end management. It's a good tradeoff, I think. Hot feet didn't get nerfed, and a lot of fire/psi's damage actually came from hot feet. If you don't mind jumping around it's pretty close to what it was before. Single target damage has gone up. Not a ton, but I definitely notice the increase on my Ice/Psi. ST gets a lot better with high recharge, but you'll never be doing the same ST as other doms. But hey, you'll have imps...The ST difference is particularly pronounced at lower levels; I can actually stomach doing ouroboros arcs on my new build.
I think energy is just really popular right now because people always secretly wanted to use energy because it looks cool. Now that it's a decent set they're making tons of builds that use it.
For /psi almost all of the powers are useful now. The only one I wouldn't consider slotting is psionic dart, and I wouldn't take it either if I had a choice. Mind probe is definitely your most important leveling attack. TK thrust is also important now for fighting robots etc. Mental blast is good to take for leveling, though you might consider respeccing out later. Definitely take psychic scream, and take drain psyche at 20.
I think the snipe isn't very useful even with the new damage, but some people like it. I found myself just using it as an IO mule most of the time, so I got rid of it.
