I know how bad the ratio is. I saved crystals and have a seven star sion. I originally was only going to go to about 4 star but got lucky and got 145 from my first pack tgen managed to get him 6 star before the packs ended. So 100 shards at the store prices wasn't terrible. I'm actually hoping he's in a fairly difficult position to farm since i put resources into him already. I just got him one away from g12 and the rest of the team except thrawn is at gear 12 maxed out and one zeta away from the whole team being zetaed which i should have tomorrow. After putting so much work into them I don't want him to be as easily farmable as kru. But I agree with you that nihlas isn't worth buying from the store since even refreshing his node is cheaper. The only time I buy from the store is if it's the only place available and it will get me another star level for me to deem it worth it. Most likely sion will be a hard node so the headstart was worth it for me but other characters like holdo, rose, and vistas marr not so much.
