Well. There's a bunch of things you need *constantly*, like Death Ward, Imp Haste, Impervious Sanctity of Mind and Chaotic Commands; but the game lets you hotkey these. And I've been doing this for over twenty years. I am *so* used to it and fluent in the game with the hotkeys that way, that this no longer takes any effort on my part.
We all have fun in different ways. I used to enjoy doing stuff like that (although not to your degree), but not any more.
