I think that if you’re not doing a lot of pulls, you can get some mileage out of Quintus. With your glut of materials, I’d go ahead and do him. Even if a better one comes along, you haven’t really put yourself behind.
If you have a shortage of either damascus blades or tomes, however, I’d hold onto my mats.
Not sure it’s worth… my Quintus hasn’t seen action in a very long time… yellow tank wars are a thing of the past, he’s not making it into purple mono, not even in vf wars. Unless some amazing yellow tank turns the tides, I doubt Quintus will ever get field time.
I had no one else to level and plenty of mats. I leveled mine. Used him for the first real time today in rush war. Nothing spectacular. But glad I leveled him.
He’s mediocre and deserves a buff like since 1 year ago. Yet I have one maxed with costume at +20 emblems and he’s usable like that but he could do better for a slow hero (not mentioning costume bonus +20 emblems and still being kinda weak).
