I would think Rosalina would be top tier but I have a feeling she'd be like mid or low mid tier. Her puppeteer mechanic is lovely but you have to hit them like 50 times to even get to the point where you can KO them.
I am still maining her anyway. I use her fire flower alt because it looks like she's a white mage.
I would use palutena but they gave her the most garbage default moveset. The other moves she has are good but they gave her Auto Reticle as neutral B, the reflect shield as side-B, counter as down-B, and Teleport as Up-B. Why would a reflect shield be a side B move, usually side B moves are moves that move the character somewhat or an offensive attack.
And you can't use custom movesets online and apparently the option will be banned for tournaments.

There hasnt been an "Real" talk of movesets being banned yet. The best arguement against them though is that it takes a while to unlock them, and you cant garentee that a setup will have your moveset in tournament (For Wii U). Plus there is the issue of do they have a banned list of moves.
Honestly though it WAAAAAY to early for a teir list. Hell project M 3.0 has been out half a year and we all have pretty different impressions about the cast then we did that long ago.
