Who should be my first rank 3 6*!

Jona305

Just did my initial abyss completion and got a tech t5cc. I’m about 25% away from forming any other class. Who should I rank up for thronebreaker or should I wait?

Being that close, yeah I'd go mysterio duped. He hits like a truck, damage reflection, power burn, poison and Immune to AAR when helmet is active. Your next R3 wouldn't be far behind and the extra materials would come faster.
