The issue of Focus starvation, if you are to continue with your full ST ‘rotation’ while also focusing on AoE, as BM, it isn’t a new one. Nor would the above make it any worse. Essentially, the idea is that if you focus on AoE, then you’d do well to skip 1 Cobra Shot inbetween Kill Commands, and instead use that Focus for Multi-Shot to maintain Beast Cleave.
In regards to the duration, you usually have time for 3 GCDs during each Beast Cleave-window. One of which is always taken up by casting Multi-Shot to activate it. Ofc the practical side varies depending on whether you’re running with Killer Cobra or not, specifically what abilities you get to press X amount of times. But either way, unless you’re in a BL window, most likely you won’t have time for 3 additional GCDs, aside from the one triggered when casting Multi-Shot.
As for a possible solution, I’ve posted versions of this several times before, incl in the main feedback topic. They can easily add a new effect to Multi-Shot, where if you cast Multi-Shot, this reduces the Focus cost of your next Kill Command by X. Or something along those lines.
I agree. Though the proposed changes wouldn’t result in the 4-set being solely focused on AoE.
- 4-Set - Killing Frenzy - Kill Command critical hits increase the damage and cooldown reduction of your next Cobra Shot by 40%. Kill Command now benefits from Beast Cleave, allowing Kill Command to strike all nearby enemies for the duration. Deals reduced damage beyond 5 targets.
I intended for the old 4-set to be kept, in addition to the new bit about Kill Command and Beast Cleave.
