Macro would be better (simpler would be a better word lol) if it would repeat skills if interrupted and also not hang if mob dies during macro. Otherwise chain is for sure best route in my opinion. No need to branch off you can use a comma so it will fire following skill 1 or 2 then continue the usual chain. Yeah a ogcd is best if you have one available but only if it helps burst during wildfire.
p.s. If I get around to it later I will try this out and see how your opener is setup.
