From earlier in the thread:
Just in case that isn't clear: it doesn't matter how long it takes to kill something ...
IF you're just going to sit there and do nothing after, while you wait for the respawn. Since Verant never put a ton of named mobs with good loot together in the same room, and mobs with good loot tend to have significant respawn time, there's a practical upper limit to how many such mobs a Shaman can farm at once (and even within that limit there is diminishing returns: you kill the mobs with the best loot first and it gets worse from there).
The "most clustered" nameds I can think of are places like Seb Crypt or PoM A4, where you have several nameds in rooms close together, and if the server isn't busy a single Shaman can do all of them. It's been awhile since I did Crypt, but I do A4 all the time (modulo 22; he's not worth the hassle to me). When I do, I have like half an hour of sitting on my hands after I finish, so there is
zero benefit to killing the mobs any faster ... and having 35 minutes to sit on my hands.
So look, you can calculate numbers on the back of a napkin all you want, but ultimately the in-game context matters. If that context is that you're farming HQ ore in Permafrost by killing low level mobs, I'll agree with you: you
should Regrowth yourself to kill faster
