Practically the same character. Can't wait for the Lucina and Marth merge. Maybe Mario and Dr. Mario as well.
Do for one means do one for all.
I may be a Lucina main, but I don't visit the boards. (I'd probably not like how they go about things, but that's TBD) Nonetheless, I disagree with any of the 3 merging. Their properties are different enough to make strategies, approaches, neutral game, etc. different. Merging any of these boards seems incredibly stupid. They're separate characters for a reason, therefore, they should each have their own board.
To be fair though, Dark Pit and Pit share everything but two moves, with one tilt simply being a bit stronger for Pit.
As for the others, the attacks may look the same, but they are vastly different in proportion and power and use.
Exactly. I'll say that: Dr Mario is the least similar of the 3, but that's due to him being based off of his Melee self. Lucina SEEMS similar, but properties change everything. (After playing both, I've realized they both extensively, I've grown to learn this). Marth = Tippers and Technicalities. Lucina = Balance and Consistency. As for Dark Pit and PIt...I'm not to certain, I've always seen Dark Pit as a powered up Pit, but slower Pit. I could be wrong on that though, don't' use either at all really.
