It may look self serving, but it is when we play things that we get to notice them.
If you look at this perk, compared to the other fighter perks, it is alright. Up to lvl 5. I think the +2 VS. Mind effect is nice, but a plus would put it more in pair with most of the others, from the point of view of balance (which I understand is not always a parameter).
At the top of my head I can think of 1/day ultravision for lvl 8 or +1 will instead of +2 mind affecting.

What it may seem to lack in pure buffs through the level variations, it more than makes up for in the special ability associated. This is one of the stronger fighter perks, it's not likely to be changed to be better.
Yes, after playing a bit more, I came to realize how stronk it can be. Scratch the suggestion.
Thanks for the attention.
