I get where you're going with the response. Rogue is the #1 single target dps machine. But I wanted a mage playthrough to see how certain decisions play out.
I've come to the same conclusion. I have seen countless threads discussing how the rift mage dps is superior given the +30% damage to weakened mobs, but all too common to have weakness not applied, or shock interfering, or worst case a fire-immune mob. Stonefist is bugged. And the real deal killer for me, was that spirit blade has utility for countering guard.
Fight a heavy guard / fire-immune enemy as a rift mage and you'll see how weak you feel spamming stonefist.
I also really think the firestorm damage is super awesome, until you realize dragons move out of it too quickly, and there are quite a few fire-immune mobs.
I admit the KE isn't super high single-target dps, but I feel extremely tactical when I'm playing my KE. As a commander, I do not feel success unless my entire team survives an encounter without dying. People love to post the super-slow solo nightmare kills of KE, but I find the real struggle as a KE in keeping my team alive while countering barrier/guard, and dps'ing when possible.
While Rogue is dps king, KEs can do very high single-target dps. Here's an excerpt of a post I made describing how I like to play my KE:
"I point my quizzie towards the demon, trying to angle my approach so that I'm in line with any other close by demons. Just as it charges up (or a wraith or despair demon shoots a bolt at me), I hit fade step. The instant I pass through it, I torque the mouse and 180 back into it, hitting it with frost step twice. I materialize, hit fade cloak, and drop a fire mine. As I fade back in, the pride demon is hit with massive spirit damage. I swing my blade once, twice, boom! the fire mine explodes. I hit fade step again, immediately whipping the mouse to zoom in a tight circle, again causing frost step to hit twice. Fade cloak again and drop an immolate and slash the beast again with my spirit blade.
Really, really, really fun times."
As for being a commander, I used to feel the same way. In Origins, I would save before each encounter and if a companion went down, I would reload again and again until everyone survived. Eventually, I realized that while a commander is responsible for their troops overall, the individual troop is also responsible to fight and survive to the best of their own ability. We are commanders, not hand holding babysitters. I do my best to make sure that everyone is properly equipped, has their orders (tactics screen), is prepped and ready to perform at peak capacity. In combat, I'll look out for my people as best as I can, but that's all I can do. Once the battle starts, the AI is in charge of them and I do not pause/tac-cam. If a companion does something foolish and gets knocked out/incapacitated, that's on them.
