From what I can tell a lot of the compatibility crowd didn't quite get what they wanted anyway. No one was calling for a copypasted Only War (which is basically what we got). I'm fairly sure everyone wanted some evolution of the rules, just not quite as dramatic a one as we saw in the first beta.

Well said. Also, if FFG is not looking to make improvements/additions to Beta2 , then what is the point of this round of 'beta testing'? FFG already knows that the Only War ruleset works, after all...
