I rarely play easy mode, but it is necessary for reasons already mentiond. I tend to start on normal unless it's a game in a franchise I feel I've mastered already (or if it's something I KNOW I can handle).
Bayonetta on normal mode is actually pretty tricky, especially if you're not used to the fast-paced hack-and-slash gameplay. It has 2 easy modes, a normal mode, and 2 hard modes. I never went easy (except for trophy whoring), but the higher of the easy settings do kinda ease you in. Teaches you to look for tells and learning attack patterns while not spanking you like in the harder settings.
