Not only your comment personally comes off as unnecessarily hostile but you are also expressing an opinion/complaint while explicitly stating that you don't care about what other people say.
It's pretty superficial and you are also judging something adamantly, despite not knowing how it will work yet. It just seems complaining for the sake for it.
Hostile? Complaining for the sake of it?
The very first thing I said was:
Mmm... I really didn't want this to turn into a debate, but I should know you guys better at this point, lol
I'm just defending my stance, lol. It was never meant to come off as aggressive in any way. Still, I apologise if it sounded like I being condescending or spiteful though (I can see how one might feel that way). I'll try to be more careful about how I word my post in the future.
To clarify, it's not that I don't care what people say (if I didn't I wouldn't be responding), but more that I find the whole situation silly regardless of the theories people construct. They're responses simply haven't changed my feelings; that's all I meant, really.
Dual wielding was a thing even before Roxas.
For example in the Xemnas battle in KH2, Riku tosses his Way to Dawn keyblade to Sora who then uses it with his own keyblade to fight Xemnas.
Also Riku had his own keyblade and Kairi's keyblade before he gave it to kairi. While we never saw him use it. He must have at least been able to summon it in order to give it to her.
Actually, we first saw dual wielding in the Roxas vs Axel fight (and even earlier in Deep Dive from KH1), but I get what you're trying to say, lol. It's more likely Riku did what the MoM does, and pulled Kairi's Keyblade from the depths her heart so she could use it. Buuuut even if he didn't, Riku technically didn't have his own Keyblade summoned in that moment regardless XD
