I really like the concept of Howl of the Pack Leader, but it feels rather clumsy in execution.
First, we have to generate a buff that then has to fall off to then cause your next Kill Command to summon 1 of 3 greater beasts. Between the appearance of the buff, the duration of the buff, which beast you will get, and duration of the beast, trying to keep track of all of this information as it comes and goes in an ever-shifting buff bar is quite the struggle without an add-on.
Below are a few suggestions that I believe would greatly improve Pack Leader gameplay.
Rather than a delayed buff, Kill Command should actually become Howl of the Pack Leader after 20 seconds, whether in combat or not. This would cause the ability to idle as Howl of the Pack Leader even while out of combat. This would allow us to initiate combat with Howl of the Pack Leader instead of having to wait 20+ seconds for our offense to actually begin.
Similar to how Wildfire Bomb used to work, when Kill Command becomes Howl of the Pack Leader, the icon should display which greater beast we are about to summon, and the tooltip should list the additional effects.
Lead From the Front should reset the cooldown of Kill Command and convert it into Howl of the Pack Leader. This would effectively give the Hunter a window of having 2 active greater beasts with control over which 2 beasts they want to pair together.
Another option that could improve the player’s ability to see when and which greater beast would be summoned next and which beasts are active would be to have Pack Leader give the Hunter an additional resource bar that works in similar fashion to Warlock Soul Shards.
We could have a silhouette of each beast or their face below the Focus Bar that would gradually fill up as the time before the next Howl of the Pack Leader decreases. Once full, Kill Command would become Howl of the Pack Leader.
Once cast, the silhouette for that beast would shine brightly for the duration of the beast, but would gradually empty as the duration ticked down. Meanwhile the silhouette of the next greater beast would be filling up as the time until the next Howl of the Pack Leader ticked down.
Thanks for your time and consideration.
