learn how to use your team ? I've had maps were i passed them easily with silvers and had a harder time to do so with higher rarity picks , simply because of costs. That being said , you're confusing gelius with jerome i think. Not that jerome is a bad unit btw...
For example, gelius IS the best tank in the game , and seriously outstat deine in the tank department. Not all blacks are the best at what they do
Edit : @karsuman , nobody is saying that nadia isn't a great unit. I've never denied that. I just said that gelis is the better plat. The fact is that nadia is not the best best duelist in the game for most situations. She's not the cheapest one either. Gelius is the best at what he does by comparison.
