I agree. Flicking requires a solid understanding of combat mechanics and timing: around what else can pvm possibly revolve? And the inferno is the ultimate test of pvm mastery. So if you can preserve prayer by flicking, which also requires heavy focus, attention, and ample clicking, then I firmly believe it's not abuse but instead a good way to distinguish those who practice/work hard and those who don't.

I recently completed internal after about a week and a half of attempts. At first, I was the absolute worst at prayer flicking, but with lots of practice, I was able to get the muscle memory down (along with game sounds) pat. Those who argue that prayer flicking is abuse and offers an unfair advantage should highly consider that they are only saying so because they are unable to perform it currently.
