IMO, resetting the experience bar back to 0% of the current level is an extremely small price to pay.

Even if I had a job at 90% though level 79 and it got reset to 0% I wouldn't care. It takes no time at all to get that level anyways. Hell, you can get little over half of that level being afk 70% of the time in an MSQ Roulette.

If people care that much then push all your jobs just over the line now and your loss will be almost nothing.
