So I came back to Dominion after a big break, and after playing a bit (up to level 53/mu=0.95 - no idea where that is in relation to the community) and I just have to say, Events make the game so much more interesting.
I've now had at least two kingdoms that looked like a boring BM+X, but events made BM+X actually have interesting strategic thought throughout. One had Save, so even with no +action and no useful cantrips, there was a lot more managing what to get which shuffle, rather than just playing through. And another one was a BM+Council room (seriously, weak as heck kingdom actions...) which had Pursue and Alliance, where I spent the whole time tracking where in my deck my Golds and Council Room(s) were to set up big council room turns.
