I think you need to understand that not everyone is tryharding for "muh parses" during the prepatch.
Especially not in Heroic, in a pug.
Thus, your snarky comment about logs is completely uncalled for, as a random pug is not going to be some kind of defining "log" for the spec in general, and one person's experience is not somehow translating into the absolute law for the playstyle of every other player in the world.
Seriously. This is my experience in a random Heroic pug, not a bleeding-edge server-first Mythic guild doing Mythic. So I'm not sure why you're going on about "logs". Most likely nobody was even running logs because it's a pug.
And instead of simply explaining why you think Renew is bad, you're continuing the snarky passive-aggressiveness.
