Really, the whole thing turns around just how often "sometimes" is when it comes to hitting the wrong button "sometimes." And which wrong button we're talking about. Accidentally blowing the LB early in every other fight? Yeah, okay, macro some stuff to condense your bars and cut that out. Using flank moves a couple times a fight when you should be using rear? Clipping ToD a few GCDs early? Screw it, macros aren't going to be an improvement.
That depends on just how you do it. Macros only interrupt/interfere with each other, so if the off-GCD moves aren't macro'ed, having the on-GCD moves macro'ed wouldn't have any effect on them at all. And if you use fall-through macros instead of macros with waits for the GCD moves, you wouldn't have any macro "running" to worry about interrupting anyway.
Between the two, if I had to go with one, I'd personally go with fall-throughs. They'll glitch sometimes and use DK or Boothsine even when TwS or TS are available, so it's really not much better than hitting the wrong button sometimes, but either of those is most likely better than a built-in wait (plus not having to worry about interrupting the /wait).
Just spam that. The extra TwS lines will cut down on, but not eliminate, the times it glitches and uses DK when it should be TwS.Code:/micon "Twin Snakes" /ac "Twin Snakes" <t> /ac "Twin Snakes" <t> /ac "Twin Snakes" <t> /ac "Twin Snakes" <t> /ac "Twin Snakes" <t> /ac "Twin Snakes" <t> /ac "Twin Snakes" <t> /ac "Dragon Kick" <t>
Steel Peak I'd be careful about. If you're going to macro it to part of the rotation, make sure you swap that macro out for any fight where stuns are actually a thing. Personally, I'd still just stack Steel Peak with Shoulder Tackle (without any wait) instead. You're either worried about stuns or you're not, so any target where you should or shouldn't be using one of those, you should or shouldn't be using the other one, too.
