Instead of Round Robin could your macro just use a different castsequence with four nulls for each?

/castsequence Lay on Hands, null, null, null, null
/castsequence null, Lay on Hands, null, null, null
etc
Here's what I don't like about Poor Man's Round-Robin... Tap your button twice, and you've either lost Lay on Hands from 2 characters instead of 1. Also, correct me if I'm wrong, but if LoH is on cooldown it's just going to hang at Lay on Hands in your sequences until it's ready, so if you press it 10 times quickly, you'll not only waste every Lay on Hands you have, but every game instance should be stuck on Lay on Hands in its own castsequence, so when you press the Hotkey once 10 minutes later, every Lay on Hands fires. Having more than one of them stuck on that spell defeats the purpose of Round-robin


With the actual Round-robin functionality, you can enable "Do not advance for ___ seconds" on the Step and set it to 0.5 seconds or so. That way you can hit it a couple times to deal with global cooldowns if necessary, and not automatically skip half of your characters or waste their abilities if you happen to tap it an extra time.
