Your two posts have been glass cannons of a meme themselves KEKW
In all seriousness though, you can’t ignore BoD/AotG on any occultist… This and not using veterancy on soldier are classic examples of “saving on the wrong end”. You would need to invest components, augments or even entire gear pieces to fix poison/acid res and the phys res is basically lost and can’t be compensated for.
Most “glass cannon” concepts don’t work that well in Grim Dawn, because a cannon made out of glass simply can’t support shooting heavy amunition.
Chaos Witch Hunter, Witchblade and some stun jacks builds have the highest single target DPS afaik, so you are on the right track.
