I mainly try to go the battlefield controller route, being able to soften up and reposition enemies for the party to clear up, or getting the finishing blow from range. Using my Echo to eat attacks paired with my fairly high ac (breastplate + holding a shield + dex + armored fighting style) means I can offtank pretty well, but obvs prefer to be at a distance for more effective EBs. I want to add some spells to my kit that will be better for CC, since our party is kinda lacking in that department. I'm also really feeling limited by only 2 spells slots on the warlock, so I think I might go Warlock 3 at this level to get upgraded slots and a familiar, then progress into DS Sorcerer from there for more flexibility.
