I had/have a similar issue with this that I asked about in this thread,
http://forum.square-enix.com/ffxiv/t...the-same-time..
the only difference being mine was about off GCD moves as opposed to DoTs; I main as Sch/ Smn so I may of gotten use to watching my DoTs, maybe. But I agree that being able tomhabe multiple macro at once woild help, so, that you could know when to refresh a move or not. This would be especially useful when the screen is full of debuffs/DoTs and you can't see all of yours or if you should perform a move that will override another players DoT, like Dragoon, Warrior, Ninja, or Bard moves that cannot be stacked but override one another.

But please SE, could you find a way to impliment this.
