When a lamer uses the beer, they're usually cautious enough to run far enough away where they can use it without getting hit, but even that isn't needed. If you're PKing, and both parties are on low health (around 1-2 health per person) and then one person heals with a beer (they are healed full health no matter their AP), I doubt they mind being hit once, and the other person wouldn't stand a chance, as it would be 8 hearts VS 1-2 hearts.

Also a lamer wouldn't use the beers so much that they're only healed 1 heart per use. They use the NPC, and continue to lame, and most likely they'll need another beer 20 - 30 later if they're not being careful.

Also the stumbling thing doesn't really have much effect on PKing, usually if you're pressing a direction when you slash, you'll face the proper direction.
