These are good ideas, thank you! I don't think the extreme recharge you're talking about will be an important goal, but likely might just be a product of various buffs and spending on sets. Since we'll be at perma-hasten or near it before sets, I don't think it'll take too much effort to get to ridiculous amounts with a few powers.
The way we'll play this is likely going to extremely aggressive. Think of Scrappers that run off to solo the world and die, Blasters that try to stand toe to toe with Lord Recluse, Leroy Jenkins, and trying our best to make sure the most aggressive Brutes can't maintain fury. Tanks are going to hate us. The goal won't be to piss off those people or kill a Brute's fury, just throwing out examples of how aggressive I want this duo to work.
