Now that I'm breeding more and more of GP1+ Watchmen, I'm starting to think that there's a potential balance problem with the gene.

I could breed a massive horde of those, and then quickly explore islands for guardian temples, magic shops, etc. It doesn't take long to locate the buildings if I don't bother checking the chests, etc. 

And that seems like an easy way to get various premium items, such as energy drinks and magic food. 

Maybe there should be a cap to how many times Watchman can be used daily. I'd suggest ten times.
