Not something you will get here, or even if you submitted a ticket.
First problem is that this forum is not a contact point for the staff as it is a forum for players to assist other players. Yes, you do see Blues posting, but they are our SFAs who kindly offer their advice, insight and keep us hoodlums in line.
Secondly, Blizzard as a whole does not give their official anything in regards to any program or method of playing the game outside of it’s original meant-to-be-played format. Not only do policies change on a dime, and someone will absolutely dredge up a ten year old post to point and say “but THIS says I can do this!!!”, but there are also other factors and dangers of one person giving any kind of “official” approval or confirmation. Our SFAs cannot give that, a GM cannot even give that. A Dev maybe could, but they’re not the most communicative lot and that still would put a great deal on that person’s shoulders (and head, when it inevitably causes trouble down the line).
Any third-party program is risky. And while I want to say someone else came here some time back thanks to a similar post or that this particular person did things that normally folks are warned against, I cannot put my finger on it at this very second.
Everything is do at your own risk. You will not get any official go-ahead on the practice or the software, no matter who is tweeting about it. But me personally? No way would I risk my playtime over something hypothetical.
And while it’s not particular to Parsec or Terran specifically, this post (with plenty of snippets from one of our SFAs) pretty much covers the lot of it.
