So I got really luck with the last banner and pulled Robin (Grima) and he is a beast. One of my favorite units, he's already level 37 and I went to arena duels for the first time. I'm currently on tier 7 and hope to play some more.
I've actually been getting back into Fire Emblem Heroes again lately and I forgot how much I enjoy playing it. I never thought I would put this much time into a mobile game.
