The drawback of the crawl idea, in my opinion, is the duration of DnD relative to the amount of movement required on certain fights or chain pulls in M+. An alternative would be to allow the benefits of DnD/Defile to linger on the player for a few seconds after leaving DnD/Defile, but no longer than the duration of the actual spell. That way movement is not a 100% loss, but careful planning will optimize the uptime.
Regardless, the underlying issue is that Blizzard decided to tie the cleave target cap to DnD/Defile. Personally, I donât think DnD would be nearly as divisive as it is now if Blizzard tied the target cap to another spell (or forgo it entirely).
A problem with this hero talent preview is that we donât know what, if any, other changes are planned for the classes going into 11.0. Earlier, I was critical of this hero tree preview for the passive power-increases, but I donât know what the action economy will be for BDK in 11.0. In future previews it would be helpful to know what class changes Blizzard is mulling in tandem with the hero talents.
