I'd lie if I'd say that I don't care about the rewards, but that's not my main concern. In my (little) experience, playing a subtier 2 with a 3+ level character makes it too easy to be fun.
But OK, I'm gonna trust you. If your impression is that this scenario is too risky to be played only by levels 1-2, I suppose it can be challenging enough.
So, ready to play :-)
