Thank you, everyone. Great suggestions! Aggroing enough enemies was definitely what I was missing. I didn't realize how important that was to keep up my dmg output with Sliver Armor. Without changing any skills, I'm now having good luck with insects in hard mode as long as I fight enough at once.
For now I'm using Glyph of Swiftness, until I can get Glyph of Renewal. I've had Obsidian Flesh in my skill bar, but I'll definitely switch that out for Glyph of Renewal when I'm not around hexes, etc.
For areas where I need Obsidian Flesh, I'm interested in using Echo to copy Sliver Armor, but if I changed my secondary to mesmer, what skill could replace Protective Spirit? The build seems to hinge on that skill. Is there an alternative I don't know about?
I'd been using Aftershock to augment dmg from Sliver Armor. What do you think of this as an alternative to Teinai's Crystals/Crystal Wave or Obsidian flame? It recharges faster than one and doesn't cause exhaustion like the other...
It appears it would be a problem to try to farm Kournans (such as the Acolytes) with a 330 ele since I think some of them have attack interrupts...any suggestions for another farming build I should look into, one that could tackle them? If an ele can't farm Kournans, what profession do you like to use for that?
Once again, thanks for the input and the willingness to help!
