I can see Larian pushing out a bunch of content towards the EA for some testing prior to final release, but I'm not too sure if they'd batch up Paladins and Monks together.

The issue with it is that it really dilutes the playerbase and thus the testing of the class. At this stage of the EA not a lot of people are willing to do 2 runs within the same patch again. Even if they made running both together easier (i.e. merc system), you're still leading with 1 for conversations, etc. I think it makes more sense to do 2 patches instead of 1.

Realistically if Larian is starting to get close to launch, they'd probably want more instances of content and news to build more momentum.
