Firstly, I'll answer your questions - yes, I've wanted the game to have a bit more new keywords/mechanics, but no, the old mechanics haven't been getting boring so far (at least for me). In fact, the game has already gone quite far with just introducing paltry amounts of new mechanics since its initial release and the developers have come up with some unique interactions/effects using only just the old mechanics.
Now, onto the keywords - I do find some of these to be a little bit interesting :)
Nightfall, which I assume works like a delayed Battlecry, can make room for some pretty interesting design concepts. My only gripe about it is that I don't like the name. Maybe come up with a better one?
Desolate is pretty interesting, although I don't like the way it's currently worded. Something like, "Immune to minions this (minion) would destroy," might be better.
Disrupt, as the name suggests, should probably just work whenever an enemy minion attacks. It isn't exactly mechanically sound (i.e. it doesn't have to be currently in-game), but it can be doable.
Madness, well, just does something. I assume the effect triggers randomly, which I don't like. I definitely don't want to see this in-game. With that said, I voted for Nightfall.
Thanks for the suggestions. Wild pyromancer and stuff would be changed to barrier.
