The main problem with your point is that these events build off each other. We've got a powerslave themed month coming up and it's not unreasonable that having 1 desert bespoke or 1 pharaoh dog bespoke could be the tipping point between success or failure and only us endgamers will have one and we're going to be the ones who probably don't need it.
I mean look at your team and quite a few of the others here, they all rely on things that were only introduced once or twice so far.
I like powerslave Hard being this difficult, the only thing I don't like is that this is yet another "the rich get richer" event.
