Going to keep this post short and sweet. I haven't been able to find anyone discussing how to use Malefic Grasp most effectively and in videos I see people doing all sorts of things with it.
The question is how do you know when exactly to stop your Malefic Grasp channel/refresh it. Do you let it run all the way down to the last tick and then recast, or do you go 1 or 2 ticks? Do you have a special method to see when exactly it ticks so you don't waste those precious ms' not channeling a useful malefic grasp?
Recently I've gone with ending it 1 tick before the final one, but I'm not positive that is the best way to go about it and then I look at the affliction logs and see how far off I am from ranking and am pretty confused how I can be so far with affliction.
