Macaroon storage structure is a bit more complex then a single file. You need to open up each file named maca* in the wtf folder (and all sub folder). Ingnor the .bak ones but all the others may have to be changed at the same time. Just doing the one file in the top directory isnt going to cut it. Unfortunatly you are just better off doing changes in game. And thats just for one character, if you look close at all the files you open you will see that most of the information is character spicific and if you want things to work the same for another character all that has to get changed also.

I didnt have problems with /castsequence ,,,lightning bolt etc. but I have not used them since the patch.

You can try ending with a comma, I really havn't figured it out if its needed or not:

I.e. /castsequence ,,heal, instead of /castsequence ,,heal

Not sure why the last command would need a comma becuase nothing follow it but if a xxx, is a "unit" that is looked for then not finding the trailing comma would cause problems.
