I did the same thing - at some point, I ended up just skipping all the Blessings and Tests of Strength; then did them all consecutively. Some more variation was desperately needed there - the Magnesis barriers and flooded chambers helped a little, but didn't alleviate the fundamental problem of the repeating enemy design. Throwing in a couple of Stalker Guardians, groups of two or more Scouts; Guardian Turrets which act more like Beamos and project a continuous beam to apply pressure while you fight other enemies; even Stal-nels using Ancient weaponry - it'd all have helped make them less of a chore. Since the shrines reset after every blood moon, there's no excuse to repeat the same enemy layout twice.
I agree about the shrines themselves. Often, I find the shrine quests much better than the shrines. There are a quite a few Major Tests of Strengths shrines that I have saved for a later session. Will try to complete them with different kind of approaches.
It seemed so low-key that I didn't realise that it was supposed to be the assault sequence on the Divine Beast; instead of a warmup to the actual fight inside the crater. Actually attacking Rudania there didn't cross my mind at all to begin with.
My problem with the escort mission had nothing to do with the actual escort, it was that I didn't realize I was supposed to use the cannon to hit the actual beast, not just the sentries. Don't feel like that was telegraphed that well, I got to the end of the path and was just like "now what?" for a while until I looked it up.
