^Actually when nv posted the above post the meta is still very buggy and not functional yet. But after several bug testing, I can now confirm that Nature Swap is 100% fully functional and playable without the 10% Nature buff/debuff. Special thanks to urkerab for being patient at fixing bugs and Matt Will for helping me bug testing. And of course nv for reviving this meta.
...Actually, we're not sure if the bugs are fully fixed yet, so guys PLEASE play the meta and let us know if there are any more bugs.
