I liked the idea of having a Scrapper with 2 damage auras so wanted to pair Spines with either DA, ElA or FA. In the end I chose Dark Armor as I couldn't think of a good Spines/ElA theme and I couldn't come up with a build I liked that was softcap with good recharge for Spines/FA. No regrets as the Spines/DA build is one of my favorites.
Someone later suggested building FA defense to 32.5% and be willing to carry a tray of purple inspira to softcap. So simple, it was brilliant. Straight to Mids' and created a build that met everything I wanted. It would have been a melee-AoE/ranged-AoE demon. Perma Hasten, double damage buffs, good damage resist, end mitigation and a heal. Will be one of the starting characters made if the game comes back.
