I've played some matches in solo queue, and my MMR's dropped a bit, down to about 85%. I'm often getting paired up with low level, newer Raiders, whilst also having high level, though not necessarily, high skill Antagonists invading. In those situations, the AI enemies were quite weak, having low health and ranged damage, and their melee strikes were only doing about 20-25 damage. Their spawn rates were also quite low. I had to play babysitter to the lower level players, though. In any case, the onus was on the Antagonist to win, but I could just clear the AI enemies fairly quickly since they were low threat.
In cases where a high skill, high level Antagonist (players I know to have been Champion of the Apocalypse level in previous updates) invades against a mostly low level Raider team, the AI enemies were still quite weak. However, trying to deal with Photon Shield Mikah, Schleuder Ginebra, or Lichtbogen Kuzmann Antagonists whilst trying to get through a level with newer players is pretty hard. Especially on levels where you have to gather Aleph/destroy objectives and the like.
I've had another game on Weapon from the Past, where I was teamed up with a 3 man squad of players who I've played with many a time before, and who I know are good players that know what they're doing. An Antagonist of similar level, though not really the same skill, invaded. The average level of all players in this game was around 115-120 or so. I was the lowest level player at 100. Antagonist was about 120, I believe.
Regardless, the AI was still greatly overpowered. Regular 5th Council enemies were doing about 120-125 damage with a melee Strike (I have about 45% melee damage reduction), had boosted health and enhanced ranged damage. I was getting hit for 40-50 damage by 5th Council shotgunners at around medium range, as Kuzmann. I guess that's around 120+ damage for non-5th Council characters. The riflemen would also kill people very quickly, and there were lots of them. Enemy spawn rates seemed a bit higher than normal.
We were basically getting spawn camped by the AI after a few minutes of the match starting, with an Antagonist running around throwing an additional spanner in the works. Eventually lost because we couldn't stop the Squid.
Not really sure what to do right now. Playing in a 3-4 man squad is pretty much an automatic loss if an Antagonist invades. Either because the system overcompensates for a low skill Antagonist by making the AI incredibly overpowered, or because the system still overtunes the AI when a high skill Antagonist invades, making it fairly easy for them to capitalize. On the other hand, playing solo queue is also mostly pot luck, and one has to deal with queue times.
I imagine Antagonist players have long complained about being unable to win against a competent, 4 man squad of Raiders. But, at the moment, it seems that you could go mostly AFK and still win as an Antagonist against a squad. Perhaps MercurySteam just want Antagonist win rates to go up more, I don't know.
I suppose players could exploit this by tanking their MMR to low levels, and then trying out Antagonist mode. If you get paired up with newer players, you could just beat them by yourself due to higher levels/upgraded weapons/knowledge, and if you get paired up with more skilled Raiders, the AI will basically win the game for you.
I find it funny that there's a stickied thread on the Steam forums telling players to organise themselves on Discord, find a group, and thus, avoid queue times. They should probably add the caveat that if an Antagonist invades your group, you're going to get stomped.
Maybe I should just take a break for a while. Not very happy about this state of affairs.
P.S. There was a bit of a strange bug on that Weapon from the Past match. There was a moment where all the Raiders' health, and my own, dropped to 0, but we were still able to move around and fight normally. Could even take a bit of damage before going into the wounded state. Moreover, the Squid's health dropped from full to just a tiny sliver. Even though it was only one hit or so from being destroyed, no one could actually get to it, due to there being a dozen or so 5th Council enemies sitting on the Raider spawn point, as well as the Antagonist.
