Hopefully they also increase the chance of a bite.
Fishing's still horribly boring when waiting for a bite, and it's not good if you have to focus on the game still.
Example: I usually fish while watching TV. I glance at the screen sometimes to recast my line if I didn't catch anything or to reply to LS speak or a /tell. I have headphones on so I can hear when I get a bite. With this new system, I can't just watch TV while fishing, as I need to do more than just hit one button so I need to pay attention to the game. So, if I only need to do something only once in a while but I need to constantly watch for that something, I get rather bored as I can't do something else while waiting for something in the game to happen.
