Macro's?

[AskaRay]

I'm using macro for my lancer right now for his 3 skills combo.

Are you guys saying that we should just not use any macros at all ?

Because right now I'm sitting very comfortably just pressing 1 and comboing 3 skills one after another (I'm lvl 28 btw )

Yes, you shouldn't do that.
The reasoning is, you can essentially "queue" skills, so for instance, right before the cooldown is over, you can press the button early and it'll go off ASAP. With macros, you cannot do this. So your combo is fine if you don't mind the DPS loss, but for many it isn't worth it.
Not to mention since the cooldown is 2 and a half seconds... but the /wait commands are every whole second, so you are losing essentially almost one and a half seconds that could've been used to attack, for every single combo. That can add up quickly.
