it seems for the past week everytime i play an STF i get the boxes on my left side of screen that say the need or greed items. i have hit both need and greed and NEVER get the items anymore. am i doing something wrong or have i missed something.
That system is common throughout MMOs. As mikewendall says, check your chat log for details on how high people are randomly rolling.
If you hit greed on an item, the game enters a random number between 1 and 100 on your behalf as a greed roll for an item. Others are rolling too. And if you were to get 75, and another person who also rolled greed got 74, then you would win. However, if even one person pressed or "rolled" need instead of greed, then they have the higher preference for winning the item (as it overrules any and all greed selections).
so what yall are saying is the bonus drops are randomly asighned to the players. so only a few people get the bonus. that sucks i am usually the one doing the objective while all the others are just randomly running around. very frustrating
