Which emblem route would you take for Hel? I got her recently and I probably would mainly use her on attack, but I see her as a good hero on defense as well.
I think typically people go defense, her mana freeze is more important than upfront damage, so keeping her alive as long as possible to fire is key.
I had her at node 9 all def/ health path. Reasons as stated by @MountainMann
I don’t find her useful on defense that much, you cannot time and target in defense.
But had to reset her for emblems going to alfrike
