While still being a beginner, I advice against unlocking Andromeda. Note, that at first SP generation is very fast from level ups - you get your first legendary soul within days. Second one in a week or so (depending how hardcore). But unless you grind hard, third legendary soul will be unlocked months in. If you unlock Andromeda, you will either lack BP from Morderd or Sniper Shot for a very long time. Not only that, but at that point, you will likely want to go for Herc as third soul... So, unlocking Andro early on, will set you back many weeks. And by the time you get to her otherwise, a lot can change in your setup with even the f2p draws. Note that dreamlitz above recommends Cassiopeia, who is on the route to D'art anyway.
