Wow warrior intimidating shout

I'm trying to make a macro that makes me switch targets, cast int shout, and switch back.I thought that the only way to do this was to make a sort of /castsequence script, but I dont know how to write it. Scripts cannot cast spells for you, and the macro API for targetting is limited to these:assist - /assist,/a - Targets a player's target.clearfocus - Clears the current focus target.cleartarget - Clears the current target.focus - Set a focus targettarget - /target,/tar - Target the given unit by name.targetenemy - Target the given hostile unit by name.targetenemyplayer - Target the given hostile player by name.targetexact - Target the unit by exact name match.targetfriend - Target the friendly unit by name.targetfriendplayer - Target the friendly player by name.targetlastenemy - Target the last attackable unit you had selected.targetlastfriend - Target the last friendly unit you had selected.targetlasttarget - Target the target of the last unit you had selected.targetparty - Target a party member by name.targetraid - Target a raid member by name.

It's generally a buy some time to cap or emergency situation button.

Warlocks can't glyph their fear to not be broken by their own damage (at least afaik, i havent looked into it). A change that should have happened a long time ago.

I don't think it needs to go so far as to work like any other fear in that it would break at a certain damage threshold.

If that's the case the best thing you can do is just target a pet or another player (totem perhaps?

I haven't actually tried to fear a totem, is it possible?
