So, with the notes from Lax, I have made some progress -

I added a Key Combination to each of the Sequence and Proc macros for the 5 specs I have in my current party. The specs are:

* Prot Pal - Seems to work fairly well, although there were 2 typos in the macro - the double "!" i mentioned earlier, and the 80-85 proc macro is split with a carriage return, causing everyone in the party to say "Diving Protection" every time I clicked the button.
* Resto Druid - Macros are no-ops, so works as expected
* Elemental Shaman - Seems to generally work, although I have not done any DPS comparisons to my old macros
* Destro Warlock - Character appears to spam curse of elements until OOM - no other spells are cast
* Arcane Mage - Casts Mirror Image, Evocation and then sits idle

So, I am going to spend some time tonight looking at the macros in detail to see if I can figure out the behavior issues.

Thanks for all the work and advice!
