@Rory If it was most damage this would happen But if it was first hit then people would just run around hitting all the mobs first then run off... What it should be is first hitting and commiting to that one. But then again in the future of full release when mobs get a lot stronger and you won't be able to 1 hit then most damage would do the trick and be the perfect system, but first hit.... that just doesn't suit me and I don't really mind the system as it is now. But this would probably be your best bet below, Another thing you can do is remove multi killing for certain mobs and make it so once you attack first you are the only one who can continue to attack (and maybe even the members of your party if you are in one) and no other player can. & If you attack a mob you are the only one who can continue to attack it but if you stop attacking for a certain amount of time it is unlocked for another player to attack then once that player attacks it just locks on him... then it just loops xD
