Why do people whine about the "removal" of Gladiator Stance? It's not being removed, it's actually going to be baseline.
What does GS do in WoD? It increases prot warriors' damage so they can compete with dps-ers.
"Damage output by tanks will be increased, and their scaling with gear will be improved. This is being done so that tanks can stay in-line with damage dealers as a group gears up together."

Read that? Tank damage will be similar to that of dps specs. Add Glyph of the Subtle Defender and viola! Gladiator Stance. Happy now?
