@Saltypatra Thanks for keeping everyone in the loop. I appreciate how frequently you've been posting game information, a great sign!
Hopeful this helps with increasing the diversity of the PvP pool. But something to consider for the future...
What about having a "featured Developer PvP Defend Team" thrown into the weekly pool as well. Or even as some kind of Holiday event. The developers could create a single customized Defend team for that particular weekly event and it would have an additional bonus to all Skills (+25% or +50%) on top of the Event Bonuses!
It should be rare in the PvP Invade population pool (to make its appearance on the Invade selection special). Winning against this featured team would include a some type of extra special reward in addition to the normal PvP gains.
