LMAO... i say SV has more luck than me, i got a couple supers with SV, that was when cracked version are still released. I also got a couple from BJX(i love it). Elites from venom.
Personally i only got ONE super warrior helm. that was 3months ago i think.
I played 4 years, made many sockets, but as far as hunting luck goes.. i feel so screwed.
EDIT:
i totally forgot about commenting on the topic. I personally agree that a IP based calculation is possible but not reasonable. It's just a waste of system resource on the server side. Most private server has different drop rates? why cuz drop rates can be set. Guess what, why do they call it drop rate instead of luck rate? lol. If you logged onto a PS that claimed to have crazy drop rate, and they be using this IP - item drop theory, then no matter what they claim it's gona be useless if you are an unlucky person, lol.
SUmming up the above, it is simply a random for cheap item drops, while good item drops might be determined by kill counters (just an opinion, reasoning on my egyco socket logic page)
