Okay, so i just hit the first 45 SC and did my initial roll spree and got this.

silver pirate
gold samari chizuru
gold pegasus stella
gold princess Themis-
plat mage sasha
plat pegasus rider liddy
silver healer
Silver archer
gold artillery zola

Also got gold Bernice off my first base SP roll

I can see a use for most of the plat/gold units, a couple of them will be regular parts of my main army, but the pegasus riders threw me. They appear to be a weaker version of Valkyries with higher cost and no UP bonus. Are they worth leveling, or should i just ignore them?
