Focus Macros not working 100% for me

[Simulacra]

there is a lag with using focustarget - change your macros to use targettarget instead and you'll realise you've been boxing in molasses all this time.

I'm curious about this claim. Here is how I understand the WoW Client-Server architecture exists today with regards to targets:

If you have your main targeted, then target something else with your main, your alts take 1/4 of a second to a few seconds (depending on latency) to "see" the main's new target.

If you have focus set to your main, then target something else with your main, your alts take 1/4 of a second to a few seconds (depending on latency) to "see" the main's (AKA "focus") new target.

I didn't know there was a bit of difference in terms of "lag" in target status changes between the two as "focus" is a client-only setting which is simply a variable that points to "target," meaning focustarget and targettarget are programmatically identical. Did you have objective results showing something different or was it just a "feel" of it? Not trying to be argumentative but when I've seen both methods work on my setup with no difference in subjective lag, and then see someone calling my method of targeting "doing it wrong" and "gimped," I tend to want to see some objective proof, aside from the obvious caveat about losing focus as a CC-targeting option.

I guess it depends on your latency - what's yours? mines 430- out here in 430 land it's noticeable, there's no 'feel' about it, with focustarget I'm shooting the old target, with targettarget I'm shooting the current target - which I guess is objective proof that targettarget is quicker. If it's faster in a high latency environment then it will be faster in a low latency environment as it's inherently faster. At one point this was common knowledge and focustarget was only used for healing/cc where you didn't switch targets quickly.
