User blog comment:Tenebraeh/Free Unit of Choice Question/@comment-28011287-20160328165018

Avani is really fun to use, but honestly, I don't really find myself using her anymore. Obviously, she's great for sparking, but I think there are better units for overall damage and utility.

Charla is good too, but I find it tough to give up a whole unit of offense for healing and buffs, as her Bursts don't do any direct damage. I can also cover parts of her buffs with other units (Avani, for example).

You can't really go wrong with either of them, and if I were to choose between them, I'd go with Avani, mostly because there seems to be a lack of great earth units.

As for the free unit, I'm debating with Dolk, Laberd, Griff, Julius, Lafiel and Klaus. I'm leaning toward Klaus because I don't have a great damage taken->BB buffer, but I really want Dolk or Laberd, even though I have Gazia as a mitigator already. Tough decision.
