DoRandomToggle in Hotkeynet and wow

[Jubber]

I am a little confused how dorandomhotkey and castrandom are similiar or circumventing blizzards change. Castrandom was changed so that the game itself wasn't making the choice of spell to cast for you based off of cd.
Dorandomhotkey just pressed a random hotkey correct? if you put 123 it will just pick one and hit the key.. you still have to put a spell/macro into the key that the hotkey is going to activate. Hotkey doesnt look at cd's and what not its just gonna click a random hotkey that you listed. so even if that fireball spell is off cd.. there's no guarantee that it will be clicked the moment it is off cd.. it could be 3-4 more presses in.
I guess thats the confusing part for me. It seems to me that hotkeys "random" is a true random as opposed to wow's simulated random.
