I don't practice scales nor do I know where the modes are. What I do know is what the main ones sound like (major, minor, pentatonic,etc) so it's not overly difficult to find them in whatever position I find myself in.

And there my point is made.
All replies to my post are relevant and valid. However we all have to accept that there are players out there who neither want to or need to spend time learning scales and modes. There are no shoulds or shouldn'ts in life. If you do something there are consequences. If you don't do something there are consequences.
If you spend time learning scales and modes, as has been said, you will be a much more flexible and adaptable player. If you don't you won't be. Neither is right or wrong. I spend time learning scales and modes and enjoy my playing more for it. I also don't feel stuck in a rut. But I do defend the right of those who do not wish or need to spend the time learning such things.
