That's a total of 47 keybinds.. My enhancement and elemental specs has a total of 42 keybinds and my resto spec has a total of 46 keybinds. My elemental in total have a possible 45 keybinds from spells in the spellbook alone and Resto has a total of 46 keybinds in spells. (This is my current talent selection, so this can vary as well)
Then you add stuff like macros, mounts, racials, etc., and remove crap like far sight, primal strike, etc. and I'm at 46 keybinds as Resto. Though I do have two mounts keybinded (ST and CT), with CT being repair mount and ST being Flying and ground mounts (Macro).
Honestly I don't mind having 46 or ~42 keybinds, since I enjoy optimizing my keybinds as well. Like having CL as C4 as resto and recall totem as C3 as elemental. It is an additional way to optimize my character.
