Which is fine. That's a matter of preference.
Spouting the trite "clone Marth LOL MORE LIKE MARTHA AMIRITE" nonsense, however, is really misinformed and insulting.
Sorry, I really should have worded my text better since I didn't mean to come across like that. Aside from what I already stated in my last post here's what I really wanted to say:
I am kind of afraid that if she'll be in, the development team might go the lazy route and just make her a Marth clone which - I agree - would be a complete misjudgement of her as a character. Luckily, from what I remember, Sakurai already said that they wanted to get rid of "clone" characters for exactly such a reason.
And the last part about Marth being girly was really just that - a jab at Marth for being so incredibly feminine - I didn't want to imply her being obsolete because of that.
I do have to admit that I came across like a dunce with what I wrote so again, sorry if you felt insulted by it - and thanks for pointing it out.
I have a question for the people here. Assume in this case you know your decisions would come true and that this is the only input you'll have on the game. If you had to chose between Robin or a Chrom and Robin duo, which would it be and why?
You know no details about either possibility, only that you must chose between the two.
Robin because there's more possibilities for him/her in terms of gameplay. Pretty much the same reason why I'd want Robin over any other FE character.
