Logs are ranking me as a Fury when I'm tanking

I looked at your Onyxia encounter, and the warriors who were classified as Tank spec used Shield Block, whereas Cleavis did not.

I did some digging through the forums and found Classic WoW Spec Detection
It looks like the logs identify your spec if your shield-using-abilities are greater than a certain threshold.

I don’t think this is the best way to identify who is a “Tank.” Instead, I think the criteria should be based on Non-Environmental Damage Taken (the top 3 Damage Taken players are Tanks) or Number of Melees Taken (either the top 3 players who took Melees from the boss, or a certain threshold of Melee, say 10+ Melees = Tank). Would love to hear some feedback.

In the meantime, is there any possibility of changing my spec on my logs from Fury to the appropriate Tank spec?

Thanks again!
