Tradeskill parser
 

I doubt it is possible, but we never know without asking.

Is there a log file for the tradeskill? If yes, can someone parse it to help the player find out the best buff to use in every circonstance?

Tradeskill results don't get outputted to a chat window, so there's no way to log it and none to parse it. On the bright side, it's relatively easy to try a bunch of combinations and see what results they normally give. (Ignore the sig on this one, 41 Alchemist alt, I actually do know what I'm talking about. ;) )
