I had no problem with etherals, but that might be because I encountered them quite late in the game and my crew had LOTS of psionic skills.
One thing that bothered me though, is that in my version, when a soldier gets TOO good, ie. his time units goes past a certain point, they wrap around and suddenly he only has like 10 timeunits.
Then you gotta just keep him around until he has earned enough timeunits to be playable again. Same goes for every other stat, suddenly he's über weak and can't carry a pistol.
