Well, people look at it like this:
In the past events the only way anyone has gotten any items in the fel events, is by killing JINX's alts or close guild members. And upon investigation of event matters, JINX is always the first person into any event related places (riddle rooms and the such). Now I understand he is a very in-game wealthy player, and that he has attained a lot of his wealth via his wit and cleverness. However when someone runs into an event last second, without being around for any of the precursor spiel and hints required to fabricate plausible answers to riddles, and "guesses" the correct answer that teleports them to the event room, where they get first dibs on anything in there, on their first try, every time. It begins to kick flags and raise suspicion.
Then you take other EMs, such as Godiva, where players other then JINX and his alts and close guildmembers attain overly rare and unique items, leaving JINX and the such in the dust crying about the "unfairness".
These are the things that lead to such nepotism related suspicions. And are only a couple examples of many such "coincidences".
A person once told me, that coincidences can only happen so often and that eventually the truth behind a matter comes out. All it takes is someone to sit back, watch and put the pieces together.
There seems to be much misunderstanding or ignorance from this post. This game is made up of different age group, maturity, intelligence, and invested time. People with high IQ and dedication will do far better than the latter. That's why there is only 1 Michael Jordan etc...
I have seen Jinx's progression in the rare collecting profession (If there is one) from day 1. I knew him before he owned any rares and use to sell me rare trick o treat items. Even the first few event items he gotten at the beginning of this career he sold them to me. As time went on, he realized those things were nice to collect and beginning to figure out the lucrative side of this profession. So he did what anyone with above IQ would do which was to get his friends and guildies in on it as well. More people attending events more chances of getting the rares; simple math.
But by watching me playing on every shard, he further invested his time into developing more characters and transferring them off shards. Now here is the important part, nothing prepares you better of becoming an expert in any area than simple repetition. In the past 3 years, he has probably attended nearly 1,000 events. Just that alone gives him and other players like him the edge. While in our eyes he is no different than anyone of us who practices this method but to someone like you or any non-regular-event goer it may seem as though he always has a head start and knows how to figure things out.
As for EMs knowing who he is that is completely understandable, he is known as "Jinx" on every single shard. But I can guarantee you Jinx has no idea who they are.
Lastly, as for unique items, go look at the Event Item list under Baja shard. Very seldom do the EMs ever drop an unique item. Most drop counts are in the 10 range and nearly half of those goes to the X-sharder players; since they have the same thoughts in mind.
If you still have doubts let me show you how many of these Baja events are attended by X-sharders:
Blend
Shu Shu
Ixtab
CoCoa
Linemen
Demonous
Sundia
Restroom Cowboy
Olchere
Nails Warstein
Promethia
Duff
Ultimakong
Wolfie
Blue Amber
Deimos
Any one of these use alias chars and are at the top of their game for events and are always at our events. But don't worry we do the same to their shards too
So in a nut shell, if you want to be competitive as Jinx, get your guild to support you, attend a thousand events, then you just might get there.
