I don't know about useless, but I wasn't exaggerating with 20 keybinds...

And I still struggle to find places for things. It sucks for a few reasons:
1. I play on 5-7 characters pretty regularly so it gets CONFUSING AS HELL
2. Finding a place for an ability that I might REALLY NEED but only VERY RARELY USE is a nightmare. For example, I don't have a spot for Master's Call on my hunter. But it would be really helpful in those PVP situations when I'd need it--but adding it to my bars would mean getting rid of something else that I'd potentially need.
Seems to me like a good cleaning up of skills that included combining some would make a lot of sense. It really irks me how druids have 2 different versions of everything. And they don't get separate top action bars for forms. Leads to a LOT of macros--which is needlessly complicated for the user.
