The biggest loss was my left click/right click trap macros - Trap Launcher uses a version of the spells with a different spell ID, so if I hit Trap Launcher, my traps grey out on the bar if I'm using a macro to stack them onto one button.
This is what I'm left with:
The Shot Rotation /castsequence
#showtooltipWhat changed: It's still not optimal, but this will keep your Improved Steady Shot buff up and get you back to your Chimera Shot cooldown with enough focus to use it, while not completely ignoring Arcane Shot. If you've got Rapid Fire up, you can probably squeeze in an additional Arcane or Steady depending on your haste and focus. Aimed Shot is now mostly used when Master Marksman procs (a depressing development, since it is our level 10 specialization shot, but our signature shot is Chimera).
/castsequence Chimera Shot, Steady Shot, Steady Shot, Arcane Shot, Steady Shot, Steady Shot
/script UIErrorsFrame:Clear();
With the changes to Kill Command and Silencing Shot, you no longer want to bind them to things. Kill Command you use but rarely, if ever, as Marksman, and Silencing no longer does damage, so you want to save the cooldown for when you actually need to silence. (Woohoo, Lessrabi!)
In other news, I still can't do the priority manually and not stand in fire at the same time. /shame
Misdirect
#showtooltipWhat changed: Nothing. Still works great. Add in the glyph of Misdirection, and you are good to go for soloing - or for picking up mobs in a hurry if the tank dies. (Oh, that Pit of Saron PUG... Luckily, I was leveling my turtle, and he was 79.)
/cast [button:1, target=focus] Misdirection; [button:2] Misdirection; [button:3, target=pet] Misdirection
Taunt the Deformed Fanatic for Kiting
#showtooltip Distracting ShotWhat changed: The mob will be different, but if you need this at some point, it still works.
/tar Deformed
/cast Distracting Shot
Fire Traps/Frost Traps
They were:
#showtooltipBut Trap Launcher has broken them. (Freezing Arrow is also gone, and Freezing Trap was renamed.) I'm going to try playing with them again and see if I can work in a fix - I really miss them.
/cast [button:1] Explosive Trap; [button:2] Immolation Trap
#showtooltip
/cast [button:1] Freezing Trap; [button:2] Frost Trap; [button:3] Freezing Arrow
Feed Pet (put the food in the appropriate slot)
#showtooltipWhat changed: Nothing! You're still good to go.
/cast Feed Pet
/use 3 1
Mend/Revive
#showtooltipWhat changed: Nothing! You're still good to go.
/cast [button:1] Mend Pet; [button:2] Revive Pet
Mount Macro: My mount macro is currently broken (pre-Azerothian flying) for all my characters except my baby hunter (ahem... Duskmoon; I have a new baby hunter) - I don't know why. Once flying goes it, it probably won't matter, since I can just drop my Nether Ray straight on my bar, but I'll hit up WoWwiki at some point and see if I can find a new one.
Random Pet (from WoWwiki)
/run DismissCompanion("CRITTER"); CallCompanion("CRITTER", random(GetNumCompanions("CRITTER")));What changed: Still works!
With the changes to spells, the addition of the aspect bar, and the removal of such things and Scorpid Sting and Freezing Arrow, we have more room on our bars now, and less need for space-saving macros. I think my priest (and her focus healing, left/right click macros) is now the only one really short on macro space.
One day I will learn, and put my hunter macros in my general macros page, so that I can stop having to copy them over between each other.
