Tanking with style

[Yeol]

now it's just load and shoot.

That is almost very FFXIV Job now. Each jobs just does it differently.

DRK 2nd combo gives MP, 3rd combo gives Blood. Blood weapon gives both MP and Blood.
If you are not keeping uptime as DRK you lose two resources not one.
If you can't constantly hit 5 GCDs in blood weapon, your are losing two resources not one.
and once that happens, almost your entire MP and blood need to be recalculated for the entire fight.

Because you missed a couple of hits before boss jumped away or missed few hits inside blood weapon, you will not be spending as much MP and blood inside raid buffs. You'll not have enough MP for TBN in some phases. Your living shadow will get delayed by and an extra combo or two, and it gets out of sync from raid buffs. Bye bye DPS.

Once you mess up, you have to keep in mind to not spend everything when they are available. You have to check if TBN is needed soon or if living shadow is coming off CD. This is the recalculation part i'm talking about. Even the duration of the fight affects the way you generate/spend your resources (example: killing ads faster)

All jobs in the game get punished. People tend to think low of DRK because of "just load and shoot" mentality. Until they realize they did less Bloodspiller and EoS in the fight.
They cared more about spending than generating. Since current DRK MP and blood generation is low, making mistakes makes it even lower.
