How many excuses do you have? Would there be a reason why you couldn't use the pro controller?
If the ous is on you to charge your shit, becuase your console is 10 ft away and nary a wall outlet in sight, than charge the tablet beforehand. We've been charging stuff for close to 15 years. This isn't difficult.
I apologize that my home theater setup is getting in the way of Wii-U gaming! I would normally have no quarrels charging daily, but for big games (Zelda, Metroid, etc), I'll probably honestly want to play for longer than three hours. So I don't want to either have to:
A) Go out to my garage, get an extension cord, and drape it across the floor
B) Stop playing for 3 hours for the table to charge
C) Have another tablet on hand just in case
And don't give me any of that get a life bullshit. I work, go out with friends, etc. If I want to spend a day on the god damned couch playing Zelda, that's my own fucking business.
I don't mind that it's 3-5 hours of battery life, but 2.5 hours to fully charge? That's terrible.
One of my main problems right here. If I could charge the thing in 30 minutes, or have a hot swappable battery pack (Nintendo, include this shit in the box with the console and controller, seriously), I wouldn't have a problem. But 3 hours to charge? Giddafucouttahere
