I wouldn't necessarily mind having the bat be about 20-30% stronger, but if they changed that it would create a bunch of people who beat it the "hard way" and never shut up about it. Not sure if I can take people constantly chiming into every thread with their "back in the day when it was hard" stories.
I don't think they could up the textures without destroying the already poor framerates even more. I swear there's a lot of dips into the mid to low 20fps range. I'm so used to 60fps that this seems abysmal.
I expected a better framerate from a next-gen game that doesn't look any better than what's already available.
I do think they should at least allow upgrading of the melee weapon.
I know it's a launch game and isn't as good as future games will look. It's been proven by past consoles that with time the games will look and play even better as a console ages and the developers learn all the ins and outs of the system.
I just think it's ridiculous that the Wii U was bragged about being more powerful than existing consoles, yet ZombiU can't even run smoothly at 30fps. That, IMO, should have been a huge priority with this game.
