Now that the pages load really fast, I have a hard time hitting 1-2-3-4-5-6-7-8-r because the combat page will end up loading before I hit 4.
What I've switched to is using the w,a,d,x keys to move, and using the number pad to kill mobs. I'll mostly just tap 3-2-1 (3 with my ring finger, 2 with my middle finger, and 1 with my index) really quick then hit r and repeat until the mobs are completely gone in a square, then move on.
hmm, then you're a slow "sweeper", aren't you?!

all I do is put my right index finger on one and slide until i hit the last number, or if there are only up to four, I just use my left hand fingers to "quadtap". AND sometimes I have to slow down, so you must be really slow to have to do that!
I didn't do the click-mania until about level 20, when I was getting frustrated, and just started clicking rapidly, and then I was like, "WOW LOL IM BEAST".... :oops:
But then I got my laptop, so the click-frenzy was out of the question, and then we got the keyboard compatibility!
