I have been a player, and a vip/founder since 2007, a lot of changes have happened since that time, but anyways, I am one of those people who has run BFE about 165 times and never got an FA symbol. What I have seen, and many other people have noticed it too is that for some unknown reason the same people kept getting FAs and other goodies time, and again, and again, and again, and again, and again, and again...
Some people who have run this instance the same amount of times as I have, or even less have gotten from 6-10+ symbols. If this had been happening only once in a while I can see that happening and would attribute it to luck, but when it keeps happening time, and again, and again, and again and you keep seeing the same people getting the symbols it is obvious that something is very wrong. This is no luck, either the loot drop table was/is broken and not working properly, or something else is/was going on.
Now, again, you have nerfed the drops to only T2 dropping FAs, and yeah you are going to say to farm some more to exchange at skirmish camps using seals for FA, but when you have to do about 200 runs to get 400 seals, and you can only get one FA this way and have 3+ level 85 toons, plus having to get the new armor also with seals, we are talking about way too much grinding.
I know some staff member or member/s, and even those who have gotten symbols will try to drop the usual lines, "we assure you, it is just luck", but luck doesn't work that way. Out of 12 people in a raid the same ones getting the FAs time and again is more than just luck, and no assurance from your part will change my mind about this fact.
Although I am not sure why this is happening exactly it is obvious that something is not working right.
BTW, this same thing happened at first with the SA drops when they came out first, only a few got many of these symbols.
Those few people who somehow get very lucky are the same ones who sell symbols at ridiculous prices, messing up the economy and making just a few people the richest in the game.
The continuous grinding is getting to a point that it is ridiculous, but, if it was true that everyone would have the same amount of a chance to get symbols and everyone was getting at least an equal average drop rate of symbols and other goodies the grinding would be less tedious.
IMO, if the drop rates of FAs were really up to luck we would see more people who do as much grinding as those who got 6-10+ symbols would be getting an average amount of FAs and other goodies such as the rare jeweler scrolls, gold class items, etc, but this is not happening. Most of us might get maybe 1 or 2 such items after weeks or even months of grinding.
I don't know how the random number generator is working, but to me it seems that it is not working right.
