For the last time, this isn't a thread dedicated to who is better on what stage. You are supposed to think "hmm, well I know Fox ***** *insert character*, but does he **** harder, or less hard, or just as hard on this stage as on other stages"
This means that if Fox vs Link on a completely neutral stage is a 7 out of 10, than a stage that makes the matchup is considered a 6 out of 10, hence the slight disadvantage, EVEN THOUGH Fox still has the advantage.
Now to arguing:
Dreamland:
Fox doesn't live any longer on dreamland than FD. On FD, if Fox doesn't hit the wall, he still often dies. Link on the other hand can still DI up, float back, double jump, air dodge, and than hookshot the bottom of the stage if necessary.That means that Dreamland is only helping one person's recovery: Link. Link, with good DI, does not die until you hit him into that wall. Killing him horizontally or vertically, is going to be harder here than anywhere else. The laser advantage on Link really doesn't mean a lot cuz Link is happy spamming right back. Its not enough to tip the scale back to neutral.
IMO- Dreamland is slight disadvantage.
FoD- This stage just messes up Fox, and doesn't hurt Link. Link actually only really likes this stage BECAUSE other people hate it. The platforms are only going to mess up your combos. Also you have no room to move on this stage, and your SHL sucks. And if anything, his spam just gets worse here.
I'm really mixed when it comes to Battlefield. Both of your recoveries are pretty lousy here. I think for now I'm gonna leave it at neutral.
