Starters:
Most common starters were Battlefield and Yoshi's Island Brawl. Prism Tower and FD were used occasionally, Arena Ferox used slightly less. Both Arena and FD were used commonly as CPs for some characters. That said, people discovered during the tournament that Sheik's recovery is bonkers on Yoshi's Island so I don't think it would get quite so many starts in the future.
All in all I think this starter list is working out well.
CPs:
Brinstar was fine, was a good CP. Discovered that Bowser can use his over-b to actually knock someone through the bubbles that seperate that stage (!). All in all was a good stage.
Corneria was fine. Rarely played in singles, more in doubles. Anyone who tried to camp in the fin area got wrecked because the moment someone gets hit into the fin they can tech and punish. It's a surprisingly good stage now, although I could see this changing in the future. I really like how walls in this game work.
Reset Bomb Forest was kiiiiiiiind of fine, but had strong signs of degenerative gameplay. You can pseudo-circle camp in the first section and there is a jungle japes style platform in the lower left where anyone approaching is basically going to get shield grabbed no matter what. It'll likely be removed from my future events, sadly.
3D Land was mostly fine and then all of the sudden NOT fine. Most of the "tense" moments came from the initial scrolling section and it had similar problems that we've seen on walkoffs. Sonic b-throw killing at 30% and the like. Will likely be removed from future events.
Tomadachi Life was a fantastic CP. Some people complained about the possibility of circle camping, but we tried for like half an hour and no one could even remotely do it. Camping above an opponent that can access you is a recipe for disaster. All around a fantastic CP.
Omega stages weren't used very often. When they were it was just to get FD with walls or to go to Brinstar for a shorter ceiling.
There aren't really any other CPs for me to potentially add to further events except Rainbow Road, which we know the issues of already. It's an awesome stage, but borderline. It will likely be a doubles only CP in the future. Reset Bomb Forest might be one of those as well.
