And your lack of queuing with your macro will result in more lost GCDs

What part of:

Make the <tt> part of the macro the default nature of the spell.
Why do i want that? So i can use my damn UI the way I want to use it without being punched in the gut for it. And YOU can use YOUR UI the way YOU want and we get an equal result.

Is difficult for you to understand?
The only gameplay change that occurs if the Devs acquiese to my request is that i can lock my target onto a party member and queue Dosis spells like any regular ability.

You want to target the boss and switch to allies constantly to heal them? You do you.
I want to target allies and have my DPS directed towards my targets target? I get to do that.

We both win. You lose absolutely nothing for this to be added and i stop losing minute amounts of DPS using a <tt> macro.
You are quite literally telling me how you want me to use my UI.

The situation you're describing and calling a "failure to fire" is because your client registers the GCD as being done but the server still sees you being on GCD. Its a scenario that occurs in every single online game that does not have queuing for its abilities. Its not a "failure" of the macro, its a simple disparity between what the server sees and what you see in the client.
My latency is a stable 147 through Exitlag, monitored constantly.
My personal habit, developed over 2 decades of playing on NA servers from Australia is such that the situation you describe does not occur because i do not press my GCDs just once per 2.5 seconds and expect things to work flawlessly.
My spells cast when i want them to because my keybinds ensure that they do.

This may come as a shock to you given your constant harping about lost GCDs and DPS in general, but lemme shout it out for you: I do not care to try to reach absolute mechanical perfection in regards to DPS
Was that clear enough for you? There a good many reasons why i do not care. Chief among them is that if reaching such perfection requires sacrificing my gameplay experience in pursuit of it, i will simply be happy to achieve "Average success" and not force myself into content where that kind of perfection is the expected play.

So i will continue to use this macro and suggest it to others who might benefit from it as i have. Right up until the Devs make it the default effect for the spell. And if they list it as part of the spell effect tooltip, it might even encourage the non-DPSers in the community that its really not that bad to press the buttons every now and again.

And you are quite free to explain why macro's can lead to DPS loss. Just try to understand that there are people playing this game who do actually see improvements to their performance when certain types of macros are used.
The macro system isn't perfect, But it gets the job done.
