So while this experiment is running why not tally this and formulate opinions on what is happening.
So far, from what I have seen, I've seen Xenos win once on big red and lost on LV twice and ice once. What I noticed on the first round was xenos were not used to the changes and tossed themselves into extremely stupid spots. On the second round that was big red, xenos were rather conservative on moves and attacks somewhat needed seeing as fire is a bitch. I should know, I was burned after I missed a leap. This makes me think that some of the tactics (or lack of) have to change now that xenos lack the massive stat boosting mutators plus the xenos need a little time to either adjust or get their mains together and stomp the marines into the dirt in a tryhard fashion. Also welcome back capture hives, no more tackle nerfs to get you down.
