Yes greninja's final smash is similar to ike's I agreed with that, I said that there was no need for similarities in move sets to exist. Greninja could have been given a different move if he can't then replace him with another pokemon there are so many pokemon to choose from
I already addressed darth pit and Lucina, darth pit was a skin in brawl and should have been kept as such no need to include him especially given the fact that palutena who is another character from the main series is in the game. If they wanted more they clould have just added hades or medusa. Lucina could have easily been replaced by other Fire emblem characters.
Like I said before I didn't think I needed to mention every single clone combo for you to get the message I thought by saying there are too many clones and given two examples(dark pit and lucina) that would be enough.
Luigi and mario are the main nintendo mascots and the game wouldn't be called smash bros. without them as in the title wouldn't even make sense
No need to apologize.
