Why you should play a healer!

[Vyriah]

I'm not.

Even if applying it to the fight is different than the dummy, there's a basis for it and the only question is "how can I find my way arround it ?". The optimisation get really steep at some point, but knowing the fight and knowing your job is already a really good start.

Also, you wouldn't even do dummy if you wern't up for a fight anyway. The way to tackle the fight is the fun part of DPS, not the hurdle. The hurdle is everyone thinking you're 12 years old because you play SAM.
Or playing BLM.
Then forget what I said, DPS is hell.

Edit :

Ah, it wasn't for me.
I'm pretty sure no one saying that DPS is faceroll. FF XIV DPS are pretty busy in their own way. But it's because they don't have funny UI with shiny new bar and count down that they have less restriction than others. they just tend to work the other way : they timers when their tool isn't up. Thing is, those are often life or death bouttons.

If messing that wildfire would explode are your tank face and kill hom giving you all its aggro, i sure as hell you would consider pressing that as something much, much more than "eh, it's just a cooldown". One time I casted earthly star on the wind III tank buster instead of the start of the second grand cross delta. That ended up in a agonizing wipe where almagest's DoT slowly killed everyone and I completly knew this would happen 30 second beforehand.
Those cooldowns are serious buisness, you have to pay respect to them.
