"@Doma: "Sentry totems are shamans' inside-joke" - can you elaborate? I never heard about it and it sounds interesting."

Once upon a time when you dropped sentry totem you suddenly became the totem, AND it stopped your movement completely. Shaman would go to 1000 needles and play chicken with the ground using a sentry totem to stop and not die.

Then they patched it to fix that bug.

No shaman has used a sentry totem for anything aside from taking screenshots since.
We have a totem so useless it is forgotten by a lot of players or only brought up as an example of the developers being complete morons. What's the point of having something that has no purpose?

The joke is that you drop something useless as a show that you are brothers in being left with a complete waste of a spell. It is also the least offensive spell possible as it rids you of control for a few seconds while you switch back. Showing trust.

If I see a space goat flagged I will often /wave and /dance. They have the best dances. If they want to try and kill me I look to see if wolves are off CD, if they are, I happily kill them, else I run for my life because without them I am about as useful in PVP as a rogue with a polearm.
