Since Castle Siege is a bad stage, let's get to our first round of retrospection! If there are any stages you feel need to be re discussed, or you just want to put in your 2 cents, now is the time I encourage you to do so!
Now that I'm a little bit older, a little bit wiser, I figured I'd throw in some of my refreshed opinions to start us off.
Final Destination -
The main problem with FD is characters who can juggle and keep us off the ground. So with slow and powerful characters with less approach options this is a fine choice. So vs. Rosaluma, vs. ZSS, and vs. Falcon, this is a pretty bad stage for us. Characters that require out camping us (With RosaLuma being an exception) or platforms to combo us (Sheik and Mario) would be hurt by this stage.
Battlefield -
R.O.B is great at maneuvering around the platforms with his projectiles. R.O.B can still hit opponents if they hide under / or are camping on top of platforms, and his uptilt is great for poking from under. SH auto cancel up airs would work great here. We do have a problem getting down from the platforms vs. specific characters, but the platforms do give us some foothold. The platforms also give us earlier u throw and beep boop kills. I really like this stage vs. Yoshi particularly.
Dream Land -
I feel that Dream Land is just "better battlefield" for us. The stage has the same platform layout as BF, but the ceiling is lower, the platforms are larger (I think), and the main platform is bigger. Also, we can do the Uthrow suicide throw if Wispy is blowing in our direction. With this stage legal, I can't think of a single reason to go to BF. I always ban Battlefield, but I never ban Dream Land.
By the way, Wispy blows whatever direction the players are on, it's not random or anything.
Town and City -
Still the G.O.A.T. It's Battlefield but the platform lay out is much better for R.O.B, and it's bigger, and we can go under it easier. Seriously, ban battlefield, keep T&C and Dreamland. I don't have much else to say besides what I said / what was already said when the original discussion rolled around.
