This feels like continually shouting into the void but I still don't know why people are asking for stacks on Blood Weapon instead of asking for Blood Weapon to actually have a buff effect again. It doesn't do anything to warrant being a timer-based buff or a stack-based buff.
It doesn't enable the use of otherwise-unavailable skills.
It doesn't eliminate the cost of certain skills while under its effect.
It doesn't change the effect of any skills by forcing a critical hit or guaranteeing a proc, or any other mechanical change.
It doesn't interact with any non-GCD skills used under its duration.
It doesn't buff damage, or attack speed, or crit/DH rate.
Putting stacks on it just changes it from an incoherent, stupidly-designed skill that shouldn't exist and is slightly inconvenient, to an incoherent, stupidly-designed skill that shouldn't exist. If that's the bar people are setting for themselves then there's no wonder this job keeps going downhill with every update.
