Mastered all weapons, disappointed in reward

So the other day I mastered all the weapons excluding SPNKr. I felt the emblem was really generic and it was only a rare, Idk if its just me, but it doesn’t make sense that you get an ultra rare for mastering only UNSC weapons and a rare for everything as a whole which is a lot harder. I’m posting the link below so you could see it yourself and if you compare it to my other videos where I mastered UNSC and Covenant weapons, it doesn’t look as cool as those.

Chief’s crest looks like one of the basic emblems you can choose from at the start of the game. Still like it though
