Canni dance with having to press the med button EACH TIME you sit...

I remember the day I first had learned about the level 35 sit to med, and it was in the summer of 2000 off of school on my Necro in Qhills killing Chanda/baobob.

So if its there from the beginning documentation might be hard to find but if its in a patch should be pretty early on
