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.
Spoken like someone who either does not play on Reboot, does not farm on a Kanna, simply plays on Bera, or already has a fully geared and farming Kanna, or is just plain ignorant. If it wouldn't really affect farming rates then no one would really bother to go through the effort to do this, they'd simply just level and farm as they go up to 200 and get into Arcane River and farming there.
This game has what? 1000 players on Steam? Which means probably even less for specific regions, like NA. The fact that people do this, especially newer players trying to just get some money in a game that's very difficult in that you have to both gear a Kanna and then gear your main, which takes ages, does nothing but simply highlight the issue.
