I used to run Andromeda in my first few months of play. But I had all my debuffs covered with Water SRs and a lot of bosses seemed to have negligible debuff resistance back then (and the game was just easier in general--I don't think I even lost a battle until Ixion Ragnarok). Also, literally anything was an improvement over Siegfried, my first tier 3 Soul. I picked up Mordred to do Ixion, and have rarely used other Souls since.
