My favorite character is Cherri from War. I love being able to predict items, and pulling off 5 clashes in a single beat is always the greatest feeling.

I haven't played as much with the Devasation and later characters, but I am super looking forward to using Malandrax a lot more. The Trap laying aspect seems excellent and neat.

When I tried Malandrax several times, he seemed very powerful to me. He's listed as part of the highest tier, but he's really not complicated at all, so I don't know what he's doing there.

I think part of the flight rankings is how difficult the character is to play against as well — so though his mechanics are relatively simple, it's incredibly frustrating for someone new to play around.

If that is the case, then he does definitely belong in Flight 5. But that seems really weird to me to set flights for playing against. It would mean that some characters in the same flight would be played badly by newcomers (and thus easy to fight against) while some would be annoying to play against (probably coz they're easy to play as). So you'd have 2 opposite sorts of characters in the same flight.

I guess part of the placement may also be the skill required to use the character to his full potential, e.g. with Malandrax, you need to be aware of the opponent character's movement options.

Fave is Khadath so far, but I've tried like 5% of the characters.

Yea there's soooo many... I stil haven't even SEEN all the characters played, so that means i haven't played even half of them. I might also add the mascot characters.
I've taken a liking to Lixis recently. She's pretty simple but cool.

the flight is not very accurate, and doesn't always correspond to difficulty level. Though his "markerless traps" is quite complex mechanically speaking.
