Sounds like fun.
It may actually be the "ocean of content" they were referring to, because if the conditions/feats are numerous enough, the different possibilities could make ever fight unique, and it's a daily thing. Good stuff. Well, except if we can roll on all the Tiers on auto, then it's back to farming. I hope even the high level players will have a challenge in the last tiers of the event.
I guess we'll have seasons as we do in GAC, where feats will allow specific units to shine, depending of the season. If seasons are announced in advance, it would give a new strategic option: should I gear units needed this season to get the feat rewards ? Good stuff too.
Looking forward to this !
