Let me know if you'd like to chat about this more at some point. I'm around.
Have my LEtools open. My build is woefully incomplete, but comparing a couple of data points:
Spell damage - Me: 175, You: 69 - Me 153% more damage
Increased damage - Me: 2200%, You: 638% - Me 211% more damage (409% more so far)
Skill tree - Me 90% more damage, 14% less damage taken (while at full stacks). I also stack disintegrate faster
So yeah, I think a few changes will have a big impact in your build. The highest damage builds for disintegrate don't stack mana and don't wear ekkidrasil. They instead wear legends entwined ring with a villatria helm + Mad alchemist's ladle + ignivar's, and stack crit and int
