I do not mean Nastrond. I'm specifically referring to the GCD rotation only here. Nastrond is part of DRG's delayed burst window and does not influence their GCD rotation whatsoever. Only their oGCDs charge it and F&C/WT maintain BotD for it. When I say dynamic finisher, I'm referring to their combos, and only that. Nowhere did I mention their oGCDs or BotD. I'd still expect it to charge up BotD's duration like WT/F&C do. In fact, I'd expect this new finisher to charge it by 20s rather than 10, regardless of where it's used. That way you aren't losing duration when trying to go for shorter combos instead of longer ones. That's the only interaction it would need to keep it functioning in the same way that the current kit does while facilitating the choice DRG needs in their GCD rotation. It has no interaction with Nastrond or LotD beyond BotD maintenance.
