Since the sequence will always reset to the start, it doesn't make sense to use the cooldown of anything other than the first entry.
For example, if, as a druid, I have Renewal with 90s cd and then healthstone with 60s cd, the reset condition needs to be 90 and not 60.

With this behavior, the sequence will only reset if it can be used again.

Yes you are right I’ll add this as soon as I find time.

@ollidiemaus Thanks for answering so quickly! I can do it myself, no problem!
From what I can see, it's inside the buildSpellMacroString() function. Is ham.spellIDs sorted so that ham.spellIDs[0] is the first element of the sequence? If so, I have enough information to do it.

@ollidiemaus After taking a closer look, it seems like ham.spellIDs only contains info about the user spells. I think there isn't a healthstone or healing pot in there, is that right? If so, the lowest cooldown will always be a self-healing spell which will be placed at the beginning of the sequence.
If those assumptions are right, this issue is already fixed but we need to update the wording of the config option to make it clearer what it really does.
