Wind really affects me in Dreamland. Of course, its mostly luck related problems, I no longer complain when out.
I play Mario, my bro Pikachu. He was holding on the ledge, and I was edgeguarding. I was spacing for a decent edgeguard, as getting too close would deal in a tailspike to oblivion, or a combo. So I got the right distance, and the wind blew me right next to the ledge, screwing me over. Or, I was standing near but not in the vicinity of the ledge, as the outside of the field around the ledge is my weakest spot and my bro's strongest. Wind blows me to ledge, I get finished off.
It also causes me to mess up my spacing, and F-Smash. It drives me so crazy. However, as I get better in the game, the impact of the wind is lessened. I'm getting more used to changes in the field.
What I hate more are Fountain of Dreams' platforms. Let's say they are down. I'm standing where one is supposed to rise, but its down, getting ready for an attack. Then the ledge rises, effectively bringing me up, and over my brother, and his tailspike. But meh, what can you do? Same thing in Pokemon Stadium.
