Soren, while you're partially correct regarding ridiculous ledge-traps on the treadmill, everything else you said is either wrong, or baseless theorycrafting. >_>
This isn't baseless theory crafting, Everything I said is what actually happens.
Every transformation promotes some form of stalling in exception for ice, you cannot jump on the wind transformation because of the incredible positioning advantage your giving to your opponent, this isn't theory craft, this is fact. Unfortunately for the characters with strong ground games their juggle games are generally subpar.(bar falco, but he's not very good in the situation still). Unfortuntately this rarely gives advantage to aerial characters either because being in the air isn't safe at all, landings are far more punishable. The only character with above average ground and air games is unfortunately metaknight, and maybe marth (and he has the option to just stall on this part of the stage, so i will say he probably is slightly better)
In conjunction its very easy to set up uair 0-deaths with metaknight, so instead of just getting your landings punished you risk losing your stock. While other characters have these combos (such as toonlink for example, you can do like 3-4 rising bairs a jump. Its ridiculous and end with up B or uair, although up B is rather risky)
Sure characters can land on hte ground faster using, glides (if I remember, this may be inaccurate) or what? Down airs? LOLOLOLOLOLOLOL. Thats simply punishable on reaction, unless you can autocancel it like sonic i guess but even then theres definetly a window to hit it LOL. If your on the ground and someone is in the air on this transofmration you have such a ******** advantage.
There are several characters that can abuse the treadmills, such as D3 who has an incredible stage positioning when he is in the middle, ice climbers can desnych blizzard as well just to name a few. This transformation is GOING to put people at the ledge, which is GOING to promote more stalling, personally i'd rather plank than approuch during that segment(i'd probably just keep jumping on belts though), even as metaknight, And if metaknight doesn't any reason to approuch (and keep in mind i'm not a very campy player) I have no idea why any other character would want to.
The rock transformation as of right now is akin to PS1 but w.e.
I don't think you understand the kind of advantage Dash grab gets on this stage Raziek. If I dash grab down throw you from the right side of the stage, we will slide all the way across and you will be thrown on the left side. This is basically saying anywhere on the stage I grab you I can put you in a position to throw you off stage. This is a great position for me to gimp people. At this point I'm basically guaranteed some stupid combo on snake, a nado + juggle on falco, Its very easy to nado diddiys recovery ( i kid you not but people don't do it) but i'm also likely to be in a position to just outright gimp diddy,and i still get that juggle if I nado. Marth isn't exactly in a good boat either, he has a strong chance of dieing or getting nair'd if he overshoots the stage. Olimar LOL, thats just asking for a gimp, D3 read snake, wario is still in a horrible position but he'll probably make it back.
And this doesn't even include ledge trap options I get from the Dthrow if I decide to play it COMPLETELY safe, and being a marth main you should know by now the advantages of keeping someone at the ledge.
I'll give you that ice climbers are pretty good on the ice segment but i can't think of anyone else who actually gains an advantage on it.
I could be wrong but the PS2 ceiling is very high, Again a metaknight bonus because generally does not kill up.
Orion can add several more pages if he wanted to.
I swear Falln's going to have a field day with this stage if its legal at socal tournaments with time outs.
But no clearly people who advocate PS2 as a starter are far more educated than everyone else on how to actually play this game.
