At Level 75, rogues get a neat new toy: Tricks of the Trade.
I remember in my days of Final Fantasy XI, it was very important to utilize your character for the benefit of the party, not necessarily for highest damage. That game was much more focused on teamwork though: you could do much more damage with great timing with skill chains and magic bursts than just going all out by yourself.
Its also true in World of Warcraft that often doing what aids the party is better than just top DPS. However, there's not as much teamwork skills. The main consideration for dps is just not pulling aggro and using party buff/enemy debuff skills.
For rogue, the only consideration used to be not to pull aggro, and on some stuff, if you need to sap. Since we have plenty of aggro dropping skills, our only real consideration when choosing spec and equipment was maximizing our DPS over the course of a fight.
We have a utility skill now however.
Now, I want to preface this with the fact that currently it seems like tanks need no extra help with threat. Current mechanics seem like it has made tanking basically EZ mode. As long as the tank is using their abilities and targeting correctly, there's not much help needed.
But, if this ends up not being quite the case, would it ever be a consideration that maybe we should spec for threat giving utility? I.e. combining max dps with good burst for tank threat?
Initial burst used to be the bane of dps existence, because it often meant dead dps, just ask a mage, but now with this tool, it might actually be a good thing.
Either way, I plan to make this a constant use skill, even no threat consideration, giving the tank +15% damage for a short time makes everyone happy.
