I noticed in the accepted answer to this question that there are some things you can't do with a sideways wii remote in Brawl. We are brawl newbies, so I wanted to ask what other things are either trickier or impossible to do in Brawl with just a sideways wii remote and does getting a Nunchuk to play with fix this.
There are quite a few difficulties you'll run into by using the Wiimote-alone controls.
Using a Wiimote-Nunchuck will fix all these problems; having a control stick really is the way to go and all the button functions are in more accesible locations (except for maybe the side taunt). Smash Bros. was simply not designed for D-pad use.
I have found it to be much more difficult to phase through floors that you pass through with the wiimote. You would have to double tap extremly fast so it sometimes takes a few tries.
Also note, performing short-hops for areal attacks (which helps reduce lag for many moves) is very difficult with the wiimote.
