You could also argue it allows for more mistakes than Cauterize/GInvis compared to their comparatively long CDs on the "f*ck off I'm not dying" part of the talents. There is also the fact that if you Cauterize with a DoT on you (Wind Step, Parasite, etc.) your healers are gonna hate you. Temporal Shield is slightly buggy and Ice Barrier can only block so much. GInvis works well but again, only once every 2 minutes.
I'm not trying to argue that CS is amazing and everyone should take it on every single fight; but as I recall GC said he wanted us to be switching talents from fight to fight and I think that T6 actually does that quite nicely as they all do well in different situations.
146*1.1 = 160; so we're (on average) 10% ahead of the class that's currently coming second on Garajal; then they are a further 10% ahead of the class in third; it's difficult to argue with those kind of numbers.
Yes, this difference is largely due to Scorch weaving; but does Scorch weaving make up ~15K dps? Doubtful. Around the region of ~5K DPS gain, sure. Any more than that and it's getting a little unrealistic.
Fire, again, has good mobility and ability to damage on the move in PvP. They sacrifice a small amount of survivability compared to Frost, but they can still CC Lock you down very well when they want to and while CM has been nerfed Pyro still hits like a truck and if you can CC a healer Combustion still puts out a lot of pressure.
It's not really a "core" mechanic of the role IMO. It's a core mechanic of Melee DPS, and even then it's only given the condition that they are within range of the boss.
Spirit Kings is only really movement for Qiang, and even then if your tank turns the boss for Annihilate you don't even have to move very much. HC is a different story but with correct positioning isn't actually that bad.
Elegon P3 isn't a great deal of movement unless you're unlucky with Lightning Pool RNG.
While Blade Lord is heavy movement I left it out purely because when you move for Unseen, no one can target the boss and Blade Tempest isn't really an issue as you can Blink back to your Rune and Scorch; yes Warlocks/Hunters/Shamans will do more damage during this particular phase but overall it's not that bad a fight for Mages.
Amber Shaper I don't find I'm moving a lot. Even if I have the add on me I nuke it from within my Rune.
Empress is actually very much RNG-related. I've had entire fights where I've not moved once and I've had fights where I've had to move shitloads; but as it's RNG I (again) didn't include it.
Smart movement is a very important thing to take into account as well, as some players would 'panic-blink' the second they are CLOSE to Fire, forcing re-positioning and putting Rune down again. They don't often think that they could stay within Rune and move a few yards and remain inside it. I would also comment on keyboard turning/moving but that's elitist and a bit harsh as well.
