Oh right do you want 3 stocks nabster?
I feel like Rosalina would be a great character even without Luma. Those lingering hitboxes should be illegal
You guys still going? Interested in a 2v2?
Super edit:
My "main selection criteria" is kind of fluid. Both "do I like this character" and "do I like how this character feels" play a role, but for me "do I like this character" can 100% trump the later.
In Smash 64, I mained Link because he was my favorite out of the line up (though I played a bunch of pretty much everyone).
When Melee came out, I didn't like the changes in how Link felt, and absolutely loved how Marth played, so I switched to him. (though I played a bunch of pretty much everyone and eventually far far later liked the changes they made to Link)
In Brawl, I decided I was gonna main Zelda before it came out. Fortunate since I didn't like the changes to Marth. Zelda was pretty awful in the game though, but I stuck with it.
And then now, Smash 4. As soon as Mega Man was announced, there was no choice. I'd have mained him in 64 if he was available. I couldn't get a great handle on how he played in the demos at Best Buy, and when the 3DS game came out, it was tough making the adjustment from my usually hyper aggressive, rush-down inclinations. But now, I love how Mega Man feels in the game, and he's really the only character who feels "REALLY GREAT" moving around to me. He has his short comings aplenty, but as far as movement and character feel, Mega's far and away my favorite.
