Oh yes, of course, but a lot of abilities and such add expertise dice in a lot of different areas xD Our other debate was just removing those specific abilities entirely, but people walking around with 6 RAW expertise skills is also not the ideal XD
So myself and my DM started really hitting the books now that they've dropped, and we really love basically everything in there, with the one exception being the expertise dice system. It's definitely cool in theory, but it just doesn't work well for our table because we play in Fantasy Grounds...
