If you're too stupid to see the first PTR build for fire mage and not know why those specific changes were made, you shouldnt be on ptr in the first place and should stick to using it to test things like whether quests work. It was blindingly obvious they were to
- shift dps from burst (combustion) into sustained
- reduce disproportionate value of crit
- smooth over rop/combustion shenanigans (which amplifies gimmicks like sinew)
Yet people screamed and cried ('omg my dps on ptr sux') until blizzard made a blog post basically saying...... all of the above. (mechanical framework changes first for x reasons, numbers later).
Problem = stupid players.
Solution =/= devote silly amounts of time to writing blogs in futile attempts to communicate to said players.
