Re: Beginners with delusions of grandeur...
I think that this experience has been beneficial to you. From what I've seen Aikido is Much more than simply throwing & ukemi, it is also a big part of how to view things. Just as one blends with an attack, one should blend with people in disagreements or difficulties/problems in every day life.
As my dojo is geared to college students it seems important to relate Aikido to things outside of the dojo, & not just the physical. Also as it's mainly visited in a university class there tends to be a high turnover rate. While I realize I may not be anywhere near as experienced as you I have still noticed this with "beginner students."
