I appreciate that you’re trying to help, really I do, but it’s wasted on me. I don’t want to be good at playing Arcane the “right” way, because playing the “right” way is not fun for me.
Sorry I thought I mentioned it, but I may have been remembering another similar post. I absolutely do Evocate and use Mana Gem. I couldn’t sustain staying at 4 charges virtually indefinitely without them. The only time I ever Barrage during single target dps is when I have a streak of too many Time Warp procs from Anomaly and not enough Clearcast or Surge procs. Outside of that, Barrage is only for cleave, aoe, or dps on the move for me (also if I have Chrono Shift it’s a way to get a speed boost and snare a target).
Also, you could chuck Chrono Shift, no damage there, and impetus (the chance of proccing over 7 AB is barely 50%).
I find the utility of Chrono Shift valuable, but I can suffer without it for more dps. In this case I’d give up Chrono Shift to take Touch of the Magi. I have a version of my build where I do just that (I know you’re probably all like "wtf dude! why wouldn’t you already have TotM??!!). But I’d rather not have to take Touch of the Magi at all if I am honest. I don’t like the “burst window” style of play that Shadowlands introduced. I was perfectly fine with just popping a nice, instant, off the gcd, Arcane Power and calling it good.
As for Impetus, because I want nothing to do with Radiant Spark or Arcane Harmony, I look for other places to get more dps, even if it’s very little. This is why I take Impetus and Arcane Familiar (now you’re probably saying "wtf dude! why are you taking Arcane Familiar?!). Since I stay at 4 charges nearly 95% of the time, Impetus is simply a 10% chance to proc 10% more damage for 10 seconds. As we are all aware, Arcane Familiar improves dps only very little (about 1.5% from my testing), but it’s the only option available to me that can increase my dps by any amount, that doesn’t require me to play in a way I don’t find fun.
The Radiant Spark/Arcane Harmony playstyle is not fun for me. I also don’t like using Arcane Orb so I avoid taking Charged Orb and Orb Barrage. I am well aware that I am gimping myself. But the alternatives are either to play in a way I don’t enjoy, or simply stop playing the game altogether.
As Garrosh said, and I am fond of quoting, “time’s change.” I get that. But that doesn’t mean I have to play in a way I don’t enjoy. This mage has been my main since 2004 (though he started out as a Human Female until we got Void Elves). I have no desire to switch mains, or play Frost or Fire. I am either going to play Arcane in a way I find fun, or I am not going to play WoW anymore. It’s really that simple.
I can’t help that Blizzard changed things so dramatically for Arcane in Shadowlands. But I also don’t have to do something I don’t enjoy. I’d rather ask for changes to be made so the playstyle I enjoyed can exist again alongside the Spark/Harmony meta. I don’t want to take away other people’s enjoyment. I just want to get back the enjoyment I already had that was taken away with Shadowlands.
Until then I’ll play Arcane my way, stay out of raids and mythic+, and do my best not to let my mediocrity impact other players’ fun.
