Mm so this season I actually finally lost some games in attack, I went from 99% win ratio to 90 or so. And the 10% losses was purely from Molly. Like I have been over several times Molly is by far the best character in the game. And its so evident by the team I lost to was not even the same team, it could be Molly and Nul(Luke Cage), Molly Groot. Etc. It did not matter so much what team Molly was with, sure its easier if shes with Invisible Women as she suck so much. But the only thing that really fucks you over is if Molly goes first and get some good critical etc. Then its over. She will just obliterate one team on her own.
But I managed to get Angela (a character I dont get why the added at all but w.e) anyway of course it was not hard as long as one gets up before 1 hour so. Then you just gain points in defence as people crash trying to attack you.
Some of the teams that was in popular this seasons except different Molly teams. Was definitely and for no reason the Pestilence X Rulk combo. Or overall a lot of Pestilence. Who still has a 100% lose chance to Emma Frost...I even put in Modok's weapon on my agent to just clear trough this loser teams faster.
Another thing was different Worthy teams, a lot of Nul and Kuurth variation were both of them together starting become quite popular.
This was a really shitty team. I don't get it at all. Nul makes you wanna attack him fast before the meteor stack gets to high, Kuurth makes you wanna ignore her because of the love ability. So the result is very clear you ignore Kuurth and Kill Nul. So Kuurth brings nothing for Nul. While for example Pestilence Nul is a lot better. Here you want to kil b oth of them as soon as possible. This means that you either get a lot of dots you wont get rid for for a time if you focus Nul. Or a lot of meteor stacks if you focus Pestilence. While they dont directly combo like Rulk and Pestilence, they both have the same danger so they make a good synergy. Where instead in the new popular Nul + Kuurth gives you nothing. Here they dont match at all. Kuurth is better with another character you do not wanna focus e.g a tank or a counter based character who either dies slowly or hits back hard. This will give Kuurth time to set up her runes.
Typically the Marvel avengers alliance Meta always show some new teams because new is better and they are often a huge liability for peoples chance to win.
