It is not about being overpowered or not, at least not for me. I am bothered with already overpowered classes that are using store stuff, like brands, tracks etc. That is Turbine's fault for putting that stuff in the store, but it is also your fault for buying it. And so far, i have seen only one monster player that is using store brands, that i can remember. And most of freeps are using them. I have encountered few champs with store tracks, minnies are no 1 at store brands etc.
