Anybody know why I am dying and how I can fix it without doing zdps?

Here is the current character. It's shock nova ignite elementalist: https://pastebin.com/ZaCVpFgt

I also have kind of a"dream" POB that I came up while theorycrafting before actually making the character in game: https://pastebin.com/UbycZ9pe

The build works pretty simply, just map with shock nova by running into a pack or nearby and cast flammability + shock nova to ignite basically the whole pack. Clear supported by fire mastery explode and maven boots. For bosses I throw fire traps as well.

I think I'm dying due to repetitive hits, which is usually the problem with going Glancing Blows. But I thought I put a good amount of regen in the build to counteract it. Maybe I drop malevolence for grace and go Ghost Dance? I never usually make my own builds, but all the fun crucible nodes this league have made me want to try it. Apparently I still have a lot to learn because I thought this character would be somewhat tanky for softcore. Anyone have ideas?
