I agree about Deck Tracker. It definitely does not duplicate what you can do on pen and paper. Otherwise, deck tracker would be a digital pen and digital paper to write, like a notepad.
Interesting enough, there are stipulations for using the deck tracker in Tournaments. Here is one of them:
…can use deck tracker so long as…
“Use of the Deck Tracker complies with all of Blizzard’s Website Terms, which include but are not limited to the Blizzard End User License Agreement.”
Seems to be some kind of logical loop. User agreement states that such programs are considered illegal unless explicitly approved, yet the tournament rules point to the user agreement as a measure to discern whether the tracker complies with it. In this case, it seems it doesn’t comply with the user agreement IF it has never been explicitly approved by Blizzard. If they are explicitly approving its use for the tournament, why don’t they state it instead of pointing to this loop with the User Agreement? They’re dodging the liability so they may do whatever they please at the moment.
So… is Blizzard asking itself whether deck tracker is allowed??? It’s almost as if they’re saying it’s ok to use as long as they say it’s ok to use, but they’re not gonna say right now, but you can look at the user agreement and decide.
These are open ended rules so that Blizzard may do anything they want at any time.
So, I think pretty much it is allowed because Blizzard is aware of it and is not doing anything to stop its usage.
