^idk lol supression is good on biosphere with pain, but supression is not better at 2 or 3 or 6 any more than it is at 1... engies have a lot of skills that are useless at more than one (rev, pain, supression), now an engie doesnt need the same amount of energy efficiency as say a commando, because of the high int, so shield and anything higher on stuff like rev is a waste again, at 34 itself you have enough points to map supression and rev or basically, there can be no "good" engie build that uses all the points to optimum benefit, its a matter of choosing between the lesser of two evils
