If you drop your pure Defender weapons, you'll see a big damage boost. You had 42% HP in your grid, which is quite a lot considering that we've had two dual-skills for Water so far (and I think only one when you posted that originally). Each Defender SSR -> Assault SR is like 10% more damage, which is NO SMALL FEAT.
Also, 30% Elemental from Relic is a shitton of damage as well.
And finally, using Sol in your team is like -20% damage. I am only using Sol because of heals for Sunday AQ and to solo Ult Fire. While I don't really want to solo Ult Fire, usually nobody from Friends and Union joins, so I often just need to...
