Don't listen to the people that'll argue over tai/nin p3n3tration's worth, people in this version have tested it many times before the forum update thing, and people playing in cn have tested it and got the same result that it effects nothing(they've tested using high gains of *ion). If that doesn't convince you, cn's official testing grounds, orochimaru's lab have tested it a couple time and they didn't get any evidence of p3n3tration working.
