I honestly don't know crap about WC Brawl lol. I know who Mike Haze is, but I didn't know that he was beating DSF and Tyrant. So his Marth is much better than I thought I guess
Also, Marth doesn't just lose to the top 3 characters in the game. He gets ***** by them. From what I've gathered (and experienced with my time using Marth as a main/secondary), Marth loses to MK, Snake and DDD 65-35. I'd probably push those to 70-30 tbh. He really has nothing on those three, and considering Snake is probably going to be at the same tier as MK, and DDD may be going up to third...it's only making things worse for Marth.
Falco has a 60-40 vs MK, 55-45 against Snake, and an I don't know what vs. Wario. He is DDD's
worst matchup. Pretty different from Marth if you ask me.
Game and Watch has a closer matchup against MK than Marth. I'm pretty sure that it's closer vs. DDD as well. Snake...probably not
All in all, I think Game and Watch should be higher than Falco and Marth, but not by much.
