Fix 4: adapt to the change, much as was done when the level restriction was first put into place, similarly to when mp3 and the ghost ship were removed with singapore. But that'd make too much sense, and I foresee you and others coming to whine at me for this post.
If you really sit down and think about it. And I mean actually think about it beyond how this is going to affect your meso-per-hour rates and whatever HOW DARE THEY you feel, they're not explicitly wrong to say that dying over and over to keep a character at a specific level to take advantage of a single map for as long as you have need of it is not an intended way of playing the game. I don't know any game that actively rewards you for repeatedly killing yourself to remain at a specific level.
