No, you just refuse to read what I actually wrote.
Right now, on live realms, tank healer combos already dominate warzones. That is a given. That is nigh undebatable.
Patch 1.2 gives sorcs/sages a love tap with the nerf bat (only to be followed by incessant crying), buffs operative heals and nerfs classes that generally counter healers.
Hence, patch 1.2 will make the healer tank warzone paradigm even stronger.
