I was thinking that there should be a few modifications for psionics for both aliens and soldiers, listed as Modified Psionics:
New Psionic Power: Mindfray: an offensive psionic power that deals damage to the target's health and reduces the target's stats (including tu's, energy, reactions, firing, throwing, and melee accuracy, bravery, psionic strength, and psionic skill) if the target fails a psionic test. Successful test means no effect. The penalty to all stats last 1 turn and can be stacked by multiple mindfrays, but the duration does not change. If blasted enough times, mindfray can kill the target. Mindfray has a slightly higher success chance than mind control.
All Psionic Powers now have a cooldown, longer if used on a person out of sight, and each power can be used no more than once per turn.
Psi Panic Cooldown (1 turn, 2 turns if used against someone out of sight)
Mind Control (Failure: 1 turn, 2 turns if used against someone out of sight) (Success: 2 turns, 3 turns if used against someone out of sight)
Mindfray (1 turn, 3 turns if used against someone out of sight)
This makes it so the aliens that keep mindblasting your remembered position observe waiting periods, and makes the AI more likely to use psionic powers when within sight.
Since it's easier to channel psionic powers against targets that are in sight, the user is more likely to succeed if he/she/it has visual on the enemy.
