Yeah, playing glass cannon style with D/D (or Sceptre/Dagger), fully offensive stat stacking, 30/30/0/0/0, running Arcane Bolt and Arcane Blast etc. worked up until around the level 70 areas – then I had to actually buy better equipment and transition to a more sensible build.
Overall I’ve found that stance-dancing (attunement hopping or w/e we call it) is vital to survival, gaining the boons playstyle from Arcane also makes you a lot more survivable and perhaps more efficient rather than the kind of blitz playstyle I was using.
I do feel slightly inadequate when a Warrior breezes by barely losing 1/15th of his health – looks kind of boring though.
