If I have a reset condition (like a basic reset=10) on a castsequence the macro doesn't work at all. If it's placed in a loop, it still loops through it to other blocks without doing anything itself. It used to work just fine prior to the prepatch and I can't find anything in the War Within post about castsequences working differently. Other macro conditionals seem to still work fine.

This is a wow bug see #1498

Also make sure you are keybinding the sequence - it won’t work now if you have a macro on your actionbar that clicks the sequence

Yeah it's keybound. Kind of annoying each sequence needs its own binding or I have to manually switch between them when I change specs.

I did miss the other ticket though. I wasn't looking at things prior to the prepatch's date and was looking for the keyword castsequence.
