This is what I think about Natsu's secret Technique and people pinning him up against two Spriggans.

I don't think he should or is capable of fighting 2 Spriggan before fighting Zeref. We saw that Natsu and his friends couldn't do much to beat Azir. While Brandish is a beast and even Marin is touch enough on his own.

I don't think he should bother fighting any Spriggan before facing Zeref because we see him holding his arm in the Spriggan's presence, he is probably judging whether to use it or not. One Spriggan will be fine but not 2 or more, he would probably end up wasting his secret technique. Right?
