However, the more one practices (at home or elsewhere on their own) the deeper they etch the samskara of the practice. This manifests as misalignment and poor actions.
This is very wise. 
I would prefer classes, but with commuting 2.5 to 3 hrs each day, I have felt that to take time for a class would be too much. I am rethinking that. Up to this point, I have taken “classes” online, using yogatoday.com because they offer a huge variety of 1 hour classes (omg I sound like a commercial) that keep it interesting for me. There is also a lot of focus on alignment in some of the classes, so I feel I’ve learned a lot that way too. But there truly is no replacement for a teacher who can give direction and corrections in alignment. What I think may feel or be right, may be a bit wrong, and only an educated teacher can see that.
Sadly the logical yoga studio for me may not have teachers of that caliber. I took one class there, and the instructor read her poses from a piece of paper. She did no alignment corrections. I was disgusted. I thought, I could have done this with a video, it would have cost me less, and at least THAT instructor would have at least spoken of correct alignment. ugh.
So - I will give that studio another chance - that was two years ago, maybe things have changed! It’s my only option for true classes at this time.
Otherwise, I’m going to just buy some classes from yogatoday, 4 bucks each and transfer them to a thumb drive so I can do them in my living room, using my playstation. Well, my husband’s playstation. lol.
