Big Payoff or Big Ripoff?

Here is my first energy run at this Big Payoff job. Based on the initial results, I'm thinking it's less of a payoff and more of a ripoff.

When performing this job, there is only a *chance* that you will earn experience points - something that we take for granted when doing jobs. There's also a chance for +5 attack or defense.

I blew through 24,000 energy, and got 8,000 XP and +5 attack. That's a return rate of .33 -- that's terrible. And I could've gotten +5 attack from leveling up very easily with the 24,000 energy that I had. Oh, and I guess I got a little less than half of a Thin Ice mastery item :-/

So I loaded up on an energy pack, putting me at 30,000 energy.

Here are those results. That's .27 xp return this time, although I did get more attack and defense points, which I would _not_ ordinarily have gotten with 30,000 energy.

So 54,000 energy later, and this puppy is still only 77% mastered.

Sooo...I went ahead and got an energy refill.The returns from this run of 24,000 energy were pretty abysmal.

Finally, with only 1,000 energy to spare, I mastered the job for the first time and earned my first Thin Ice! We can master it up to 25 times I think, but if it is going to take me 78,000 ....I dunno if even I can pull that off.
