Some items differ greatly than others.
I recall running into the same guy at the "Fruit Basket Party" 3 days in a row, I had by the grace of heaven been the first one logged in and under control at server up 3 mornings straight, and he had been Number two, I would snatch the basket literally a split second before he could grab it. I beat him by that margin for the first 2 days. On day 3 I was wondering if he would even be there, and he was. The instant I saw him I started typing "Yours" and managed to get it out as soon as he grabbed it. It was obvious I could have had it, but it would have been one heck of a lamer thing to Snatch it up 3 days in a row. The point is I really shouldn't have been there after getting it two days straight, and with him there, It would have been a Major lamer thing for me to do not to let him have it. There are TONs of server up rares and I could have been at any others. If the same person keeps getting the rare before the others, pretty soon someone will Log in with their PK instead of their rares hunter and Put an end to that!
There is the PK factor in Felucca, however there are not anywhere near as many PKs up early (Server up) and at spawn sites as one might think. In fact I have seen more PKing happen from one Rares hunter to the other because one was being a lamer. The Obvious solution is not to be a lamer.
If you hunt in felucca for Server up rares don't be a hog!
Because I want to try several locations in the first 200 seconds that the server is up I take a rune book (loaded with recall scrolls, I don't need to cast recall but its faster to hit the Button than flip pages)
If your not using a rune book (Rune books are newbiefied, they stay on you when you die) its one heck of a pain to mark these again if you do happen to "buy the farm". By only hunting in Trammel for the Dungeon Rares, I will almost never Die because I can just "push" right through unlimited monsters, as opposed to felucca where I can only Push through one, then I'm trapped.
Also, I'm not up at the crack of dawn every morning. (well, more like 7ish sometimes :) I hate dieing because I won't get to check other locations without all the other hunters doing so first. And checking dungeon locations in Felucca is a Very good way to die.
I remember explaining this to a friend of mine about rares hunting in trammel, PKs, and recalling etc. The best Question he could come up with was: "Yeah but what if the Pk is Hidden just waiting for you to Grab the Item" Had we been in the same room in Real life I would have thrown my Gum at him! 1-If the Pk has time to wait for you to Grab it, he can grab it himself. 2-Odds are he is Just going to recall home and not worry about you the second he grabs it anyway.
Side note, (happened sometime in November 2000) a friend of mine after reading the above paragraph figured he would have some fun and log into the Tall candle spawn on Europa with his Red (His PK). Apparently all did not go well *snickers* the other rares hunters that showed up chased his Butt around the 3rd level of Covetous , in and out of the Lich room for quite a bit, hitting him constantly and disrupting his recall spell, he did finally manage to escape with his life (and the fear of stat loss was a Serious Concern)..... ROFL! When I picked myself up off the floor from laughing I congratulated him on his adventure and telling me about it.
He Deserved it! :) I'm ICQing him right now as I write this to rib him about it too...
