My team is BK, Dorcas, Rein and Brave Lyn. Would Myrrh be better than Dorcas or should I just save my orbs?
Eh, they're somewhat different. Out of the two, Myrrh is probably the most useful. She has high attack with her breath (and already comes with Fury 3). Not to mention her breath already attacks the lowest defense against ranged units, and Distant Counter isn't all that necessary on her, but it is a nice addition. And she has access to Guidance Seal to give Black Knight even more mobility.
Yeah, Distant Counter is a good skill to have, but people are under the misconception that it's an absolute must have for her, when it's not. Fury 3 is good as it increases her defense, which is arguably her most important stat.
For her B skill, you could go with Quick Riposte 3, or 2 if you don't have a 5* to fodder off. If you don't have Quick Riposte 2, then you could use Vantage, and give her the Quick Riposte Sacred Seal, just know that if you do that, she'll be easily shot down by Bow units.
If you don't wanna give her Quick Riposte seal, then maybe Close Defense to tank even more hits from enemies.
Myrrh is a flying dragon. Dorcas is infantry axe user. They share a color. That's it. They are so different it's not even funny.
I say pull for her, but if you don't get her unless you were making a dragon team, you aren't missing much. She's great, don't get me wrong, but you don't sound like you need her.
