In Game Character Changes

Recently, Acrobat Edge had his class changed from focus to aggressive. I have no problems with the game being changed to better balance it or for whatever reason. What I do have a problem with is the fact that the boss breaker abilities that many of us had leveled up on edge were reset to level 1 ( obviously because they are new abilities ) and we were not refunded the coins used to level his abilities before the change.

I find it unreasonable to think that the time and effort spent by the players can just be taken away. I understand why it was changed, I do not understand why we can’t be refunded the coin list due to no fault of our own. This needs to be resolved
