Constant changing of zeta skills makes it impossible to plan

I like playing clones and I put my Zetas on them since I knew I would always play them. They are not viable in arena but great in AAT and GW. Yeah it sucks they nerfed the protection regen but I would have still put it on Cody. If I had put it on jyn or someone on my arena team I would have been pretty upset. They did the right thing and refunded the Barris Zeta, but I doubt they will do it again....
