While the event itself sounds kind of neat, I can't seem to bring myself to even bother with this (or the last one). The rewards were things I didn't care about, and I'm only at 18 complete teams and 7 complete Epics, so I'll just keep doing that instead.
And, of course, I need to both finish Conquest to unlock those things, and then start over because Tampa Bay didn't have any spaces to take for the last thing I need on the Archer thing...
