I don't understand how this could be anything other than an improvement.

One of the biggest problems with claiming, only being able to claim one monster at a time, is being solved. Initial claim still determines who recieves the rewards, the only difference is other players being able to help.

I don't see how people can even bring up the idea of MPK'ing being a new problem considering this new system changes nothing that regard. Enemies will still run back to their territory, and if you happen to be in the path, you can expect to be aggro'd.

Then there's powerleveling... which has been in the game since launch... The only difference being, you can now kill multiple enemies at once.

This entire thread is made up of people complaining about ideas they don't fully comprehend, and if you have the time to COMPLAIN about an idea, you might also have time to UNDERSTAND an idea and realize that you may have fewer tears to shed.
