Remove all but final boss of challenges

[Boobler]

So since the change, you no longer get a reward in a challenge unless you 100% complete the challenge, so why not get rid of all of the fights leading up to the final boss and just have the players take on the final boss right out of the gate.  This would save so much time and also resolve an issue where people leave the challenge just because boss #4 of 5 or #10 or 13 didn't die instantly even though the party can do the whole challenge.
