There are, with out question, things that go unplublished or unreleased on these boards.
At one time, Ghost killing with rangers, rogues and zerks was an example of a plugin that was not released to the public. This in combination with Tones Don plugins, pretty much made it easy to farm crystals 24/7. I assure you, this behavior repeated server wide, greatly affected the server's crystal economy.
At one point, there was a bug with cleric swarm hammers, which was quickly turned into a plugin that allowed you to essentially hammer swam kill mobs quick - this went relatively undistributed as well before the bug was fixed.
Typically, what you are going to find is, people with mad coding skills, eventually want to get paid for those skills and thus, either do not release their plugins and farm for cash for resale to the yantis of the world, or they themselves are trying to become the next yantis.
The ghost plugin I am talking about specifically, eventually became unavailable to others because:
1. people were trying to jack the coders code.
2. he selected a person from each server to run ghost plugins for the SOLE purpose of having these people sell him their plats at a decent price, relative to the other sites which he resold himself.
So yea...there are things that the general MQ users may never be aware of that others who are talented enough, write for themselves or for profit whether selling the plugin or profit in the form of farmed plat for resale. Whats more, there are macs that go unreleased as well that are insane.
Plugins aren't the only things that go unplublished to the masses. This, believe it or not, is a good thing, and not for the reasons you would expect. I am speaking from a game integrity/in game economy integrity perspective....
When MMs first came out, I wrote a simple little mac that ran around in the Trains mission. I grew several toons from scratch to level 70. In all i think before that mission was completely destroyed, I managed to grow a druid to 70+ AAs, 2 rangers to 70 + AAs as well as ran up my AA totals on my tank, cleric, enchanter and wizard.
In all, that ONE unreleased macro netted me in the range of 200 levels and well over 2k AAs between 6 accounts. It was a tough decision. I wanted to share what I had done but knew, as soon as I did, lguk would be over run with 24/7 afk macroers which would lead to the mission being nerfed. I ended up deciding to keep it to myself to preserve my accounts as well as not draw any additional attention to the mission, which i believe others had written macs for as well......kind of sucks. Damned if you do, damned if you don't sorta thing.
I sure do miss coming home and having 20-24 x 6 AAs a day to spend though.....
