Well, this farming method is so aggravating that I'd rather go fishing. (My fishing is level 3 and I can't fish for more than 1 minute)
We should definitely not mess with fishing at the moment as when we update to 1.7+ it is going to turn the fishing world upside down. (new ebooks/fish/etc)
I think that's even more of a reason to raise the price. Desperate people will do desperate things, including really annoying stuff like fishing and vine farming. Vine farming should be raised to a reasonable price in my opinion.
Honestly, vines are the one thing I can't test. I don't have the patience for it, besides, there's no optimal farm setup yet. Without a proper farm there's no way to properly test. So until someone builds a farm, I can't test vines.
But he asked for a lock...how can you deny that? You got a whole farming discussion thread you can post the price change on...
