Maybe you should learn how to play PUP then. I've never had problems with overload. The fact that you can negate it completely by being good at the job makes it far less of an annoyance than perpetuation which can only be negated by level 90 armors.Overload is worse for the PUP than perp cost is for the SMN. Perp cost is trivial, overload is not. There are many times when PUP is only using the automaton, and meleeing is too dangerous, thus negating your alleged benefits.
And I must say I've never seen a PUP wear full time 5-10 sets of -overload armor. While seeing a SMN with perpetuation all over the armors is more of a rule than a common occurrence.
