The old hybrid nerf should be removed and replaced with a different way to stop them becoming OP.

We all know how skill point cost works, after 50 it costs 2 points, after 75, 3 and after 100 it's 5. I suggest for the skills passive psi use and aggressive psi use, the point cost becomes determined from the combined total of both these skills. So if you have 60 apu and 40 ppu, this totals out to 100 and levelling either of these skills would now cost 5 skill points.

This is just a thought I had now, so feel free to point out any problems with it.
