So what about people who use the Wii U Pro controller? Do they expect them to pick up the GamePad to type every time? A lot more cumbersome than just putting the controller away for a second and quickly typing something on a keyboard in front of you. It's not even remotely as fast as any person that can properly type on a keyboard and during battles you don't have time for this.
I seriously don't understand decisions like this one. Monster Hunter Tri on the Wii had it and I used it all the time, how hard can it be to support USB keyboards for text chat for this game too?
