I know anyone who has been in the same general area killing for awhile has noticed that loot drops off a lot. I have recently gotten Magic Find gear and noticed a lot higher quality in loot and more often, but only for a short while. I have been farming to try to get good gear for myself but some events I stop getting drops 1/2 through. It is obvious to anyone who has been out trying to collect stuff for them selves that there is an anti farming policy in effect. I would not mind it so much if ANet would actually tell us what the policy is instead of everyone having to guess and wasting their time. I have spent a lot of time and money on this game so far and this is a huge issue for me. If ANet wants to keep my business they really need to inform us so that we do not waste our time, it might not be worth anything to them but it is to me.
