Basically one of the following things will happen:
1. They can increase the other tanks' damage in patch soon and keep the same tank meta. This will make most people in this thread happy.
2. They can keep the tank damage as it is and change the META in the next raid (3.2?). Complains will keep going on until people get enough ilvl to clear Savage but will still persist until the next raid comes along.
3. They can keep the tank damage as it is, keep the same META but give some support abilities to the other tanks to make more wanted in parties. That's also something that wont happen soon. Complains will keep going on until people get enough ilvl to clear Savage but will still persist until they announce or implement the changes.
4. They can keep the tank damage as it and keep the same META. Complains will keep going on until people get enough ilvl to clear Savage but will still persist until the next raid comes along and people will start complaining even more when after the new raid launches.
EDIT:
For my part I would actually prefer that they actually change the META rather than give tanks more damage.
