TMUAR, according to AHK 250ms would be a quarter of a second. 1,000ms in a second. I’ve tried 80-100ms and watch all the spells whiz by before the GCD even gets a quarter of the way. I set mine for 450ms, and it seems to hit a spell at the right time. These macros aren’t geared for an exact sequence of spells, rather a hit the one that is close enough and ready. So, it is humorous to see /castsequence, because I’ve noticed recently that it brakes the macro and causes stalls. So, I wind up modifying all the macros that I get here until they line up pretty much with tell me when.
