I think this aspect of it is different depending on whether you played your way to mid/high level or whether you started there. If you start at level, say, 11, you're going to have a lot of options to deal with all at once. But if you "earned" your level 11, you will have started out with few options, learning how those work and what situations they work in, and then gradually integrating more and more tools in your kit.
I agree to a point, but given advancement is relatively fast, its possible to have a new level (and ability) roll through before you have entirely internalized the prior ones. I had a bit of that with my aforementioned Champion (less so with my Gunslinger).
