Ok update for me....

So far priest and warlock do not have any errors when running Macaroon. All shamans were converted to Bindpad & standard blizzard bars because of a persistent Macaroon_Buttons error that would pop up every few seconds and eventually make WoW want to disable it (got the too many errors message).

What I have been able to determine so far (and still investigating) is that the error that pops up has to do with passing a null castsequence spell through a lower() function in the add on script. I manually edited one of my shamans /castsequences to fill in "abc" between (and before) commas in the Macaroon.lua in shaman's WTF folder and the errors went away. I logged in to find that Macaroon was no longer complaining but had since restored the entire WTF folder and in my next test I got the errors again.

Does anyone know of a "null" type spell that I can use between commas that would be a valid do nothing spell? I'll do more testing and report back later tonight.

The one other concern (because I miss Macaroon on my shamans) is someone else reported having some fps/lag issues with Macaroon running. I somewhat agree because when the crazy AOE in LWG happens I would drop down to almost do fps and my LWG oRA2 autoinvite would sometimes not catch an "INVITE" whisper. Late last night after LWG was up and running I had the default blizz bars oRA2 invites were almost instantaneous with the auto invites. Does anyone else have lag or fps issues when using Macaroon?
