I have been very much looking forward to GOTM G&K.
I have also been advocating for GOTM with DLC's (preferably all DLC's, only at least a rotating amount so we can play them all).
However, I do think we should continue to have occasional Vanilla games (which is why I voted for the minority option). Vanilla and G&K are significantly different with very different strategies. I think it's useful being able to toggle between both. If you only end up playing one, your skill in the other atrophies.
I do understand that normal GOTM has been going on for quite some while, so I'd be okay with taking a hiatus from vanilla (maybe we could alternate between G&K and DLC for a little while). But I do think it's important to still have occasional Vanilla games to keep our skills sharp!
