As a Person who actually has people to play with who are all competitive melee players and RoA playtesters, my tier list is as follows:
1. Orcane
2. Wrastor
3. Zetterburn
4. Forsburn
5. Kragg
Orcane has the most versatility of any character. With a great dash dance for spacing puddle strong attacks, a realy solid ground combo game with every aerial, down Strong, dtilt, utilt, and dash attack which allows other moves to work as finishers. He forces opponents to respect space with bubbles as a hazard and extended strong attack range ontop of a puddle. His recovery is questionable until you learn how to properly use sideSpecial, air-dodges, and wall jumps to your advantage and only use the puddle when you absolutely need to.
Wrastor definitely does not need any buffs. He was so overpowered before that he got heavily nerfed with end lag on strong attacks, and even then, he's still a huge threat. I have a difficult time as any character against Wrastor except orcane who makes use of up Strong attacks as finishers more on Wrastor than any other character. Wrastor has an amazing combo game even without the air stream side special. With it, his dash attack is big trouble for anyone who can't parry consistently, and he is the only character as of now that can do double aerials out of a shorthop, which allows for ridiculous combos starting with dair or bair. In the next build which features custom controls, I have set the right analog stick to aerial attacks instead of strong attacks and set one of the bumpers on an Xbox 1 controller to trigger strong attacks and immediately I got so good with wrastor. He's definitely no where near the worst if you have a good understanding of how to link attacks into strong attack finishers. His strong attacks KO as early as 75% with a sweetspot. His recovery is easily the best in the game and also the safest in the game.
Zetterburn has a problem with fire being too powerful. It'll be dimmed down in later versions a bit once dan experiments more with balance. If it was still as ridiculous as it was a few months ago, he'd definitely be my number one pick. His recovery is his huge setback right now, but his combo game is great. His recovery gets kind of shizd on by Kragg and orcane.
Forsburn is only above Kragg because Kragg is so slow that he has a hard time getting combo's started on opponents who know how to dash dance and bait out attacks. My tier list is based on actual human players instead of playing against CPU's or new players.
Kragg sucks @
4nace
. Personal opinion, even though most new players seem to use him. He has tactics but not as many as other characters have to use against him. I'd say his only good matchup is against Zetterburn barely, and possibly a neutral matchup with forsburn since they're both pretty slow. Kragg's specials are super important to use to win anything with Kragg.

As for the random character select/stage select, that's already been noted. Dan used a method for RNG that's not very random at all only to reduce the time spent by the computer to randomly select things (I THINK). I've complained about it before and I don't think he really cares as of now with other stuff being more important to get done, like stages, new characters, music, new modes, online, etc. He'll probably get to it eventually though.
