Below 20% Kill shot macros

I've been reading the forums all day and tweaking my teams. I run mixed groups of 5 and have 1 of each class. Anyway, I am trying to figure out the easiest way to deal with Execute, Kill Shot, Hammer of Wrath, etc. i.e. the conditional finishing moves on mobs with less than 20% health.

I use /click setups for all my guys and gals and at this point I'm just using a second key binding that switches to a spam of the finisher move. I've tried to work, for example, Kill Shot into the end of my /click, hoping that it would get selected once it becomes available (when the target drops to target health) but so far I've only broken the macros. I know using something like:

/cast Kill Shot
/cast Steady Shot

worked prior to 3.1 or whatever but doesn't any more.

My last /click for the hunter is /cast steady shot and since that's always going to be available, the /click will never progress past it unless I tell it to every single press. Then it hits Kill Shot, which isn't yet available, and hangs.

My only option is to separately use these spells or add them to the /click rotation but with ........................... in front of them... trying to time it so that it only enters the rotation when the mob's health is below 20%, right? And that seems like a disaster.

Sorry for how poorly written this is. Just curious if I was missing something. Thanks, and as always, these forums rule.

Oh, lastly, are these spells actually worth the trouble? Since I can't test them on dummies, it's hard for me to tell if I should break my regular rotation for these. Certainly on regular mobs I don't even really have time but on bosses I should, right?

Quick answer is: No. At least not in the form you are attempting. As you said, no matter where you put it there's a problem (like unable to trigger /cast steady shot).

However, you can try a modifier (I know, its not an automatic kill shot with 1 button, but still worth considering). When you think the mob's health is low enough (or can tell with your UI), you can hold shift, alt, or ctrl to use kill shot, then let go of the modifier to keep normal rotation. I have no idea if breaking rotation is worth it... or for any class with low-health abilities. Might be something for the wow forums, unless other members here know.

#showtooltip
/cast [mod] kill shot
/click button1
/click button2
/click button3
/cast steady shot

use a castsequnce, some commas, and a click macros.

it works. ;)

For my paladins I just have Hammer of Wrath at the bottom of my dps macro

/startattack
/use 10
/use 13
/castsequence reset=8/combat Judgement of #Judgement#,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
/castsequence reset=10/combat [mod:ralt] Divine Storm,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,
/castsequence reset=4/combat Crusader Strike,,,,,,,,,,,,,,,,,,,
/castsequence reset=8 [mod:ralt] Consecration,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,
/castsequence reset=15/combat Exorcism,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
/castsequence reset=6/combat Hammer of Wrath,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

I'm using Jamba-macro so I don't need to have /click link to different macros
Notice how I have /castsequence reset=8 [mod:ralt] Consecration and /castsequence reset=10/combat [mod:ralt] Divine Storm, I have those in place in case I want to disable aoe effects. I have this macro bound to F9 and I have hotketnet setup to send F9 with no modifiers if I don't want my paladins using aoe, but when I turn caplock on hotkeynet passes the modifier (right alt) + F9 to my paladins thus turning on aoe effects.
this technique could be used to toggle execute style abilities too.

here are the hotkey definitions in my hotkeynet script
w1,w2,w3 are the dps, w4 tank, w5 healer

// tank only
<KeyList TankKeys 0-9, Plus, Minus>
<Hotkey ScrollLockOn NumlockOn TankKeys>
<SendLabel w4>
<Key %Trigger%>
<SendLabel w1,w2,w3,w5>
<Key f9>

<Hotkey ScrollLockOn NumlockOn CapsLockOn TankKeys>
<SendLabel w4>
<Key %Trigger%>
<SendLabel w1,w2,w3,w5>
<Key Ralt f9>

just for clarification I'm using Scroll Lock to toggle hotkeynet and Numlock while off sends 0-9 keys to all clients, and when turned on, just to the tank client
hope this helps
