I like the new events on Tribble. I use my FED Tac VA in the FED mirror events and my KDF Engr BG5 in the Defari Borg invasions. Both characters are running DOFF assignments fulltime.
My daughter likes playing the Defari Borg invasion so she created her own KDF Engr yesterday.
I discovered a neat trick this weekend. If you have rewards waiting to be collected, turn them in when your character is temporarily boosted in rank (like a Borg invasion/incursion).
