I will say again they will not make macros link, cycle, repeat, or anything of the sort. That would create to many people doing bot-like activities. Skilling magic for instance would become easy, use macros that link together to make a chain that never stops and skills you while you can afk. Same thing to an extent can be done with claiming or with ??? pops, make a macro with /targetnpc then /ja provoke <t> and you get a claim bot that always will claim whatever is infront of you so long as nothing else is in the way. You can do the same with ???s just a little different.

I am all for the idea of making macro lines be able to do this, and would love macros themselves to have more lines in general. Sadly cycling, linking, or things like them will probably never happen.
