[Psionics] Worldline Rules

[arcanus]

Hi All,
I've searched for previous threads to avoid raising the living-thread.

I need some ideas on how Psionics would be affected by different Worldlines, now I like differing Mana for Magic but I don't want to take the Mana for Psionics route as I feel it diminishes Psionics.

However don't want the Iswat super telekinetic running around scott free when the mage's fireball will barely light a match.

So what other interesting ways are there to challenge or mix up psionics on different Worldlines, an example being the Telekinetic is currently on Reign of Steel.

I like the fact that he is an anomaly and if he uses his powers too often he becomes a subject for investigation and dissection for the Zoneminds however I want to throw him a few different curve balls.

Thoughts, ideas?
