Finn's zeta was one of the best investments I've ever made in this game, and it sucks that it has to be nerfed, but with C3PO added to the mix, it was broken (it was pretty close anyway for a while there).
I'm just glad they've come to their senses and decided that if they're going to change the zeta that they should refund the materials used to upgrade it (including the zetas). The fact that they said they weren't going to before was the real bush-league move. You can justify changing the ability, there's no excuse not to give back the materials people invested in the ability pre-change.
