Team Marie here. Not enough information to say which I think might be more popular or stronger. Only had a small start tonight - I've been playing Twilight Princess intensively so didn't even realise how early this 'fest started and had a short session an hour ago to warm up for a big run to royalty tomorrow. I started out with my long-time de facto main, the Tri-Slosher, but I've been thinking of switching to the Sloshing Machine Neo before the end of my climb.
First game, Kelp, my team was three Level 50s and a Level 25 against four players in the 30s~40s. I was surprised to see that the opposing team had an overall ranking 30 points above ours; in spite of that, we won reasonably convincingly. Second game, Walleye, however, we got squished, primarily by a Zink who went 8/0. I tried to help pull it back by sneaking around them a couple of times, but they had two players who kept spamming Point Sensors - an admirable strategy.
Third game didn't happen because the lobby timed out with only one person other than myself in it. Still, those two games got me to Fiend, so, like, nice.
