Like this! Thanks for info.Each quest has a medal rating given to you upon completion. All quests support all levels of medal (bronze, silver, gold, platinum). Each Big Battle instance has multiple quests associated with it (1 primary, several randomized secondaries). The quests in a solo/duo version of a space and the quests in each of the various group versions of a space are different and unique quests, even though they may share common elements. So platinums are available in solo, and bronzes are available in raids.
Think of medals like a letter grade (A - Platinum, B - Gold, C - Silver, D - Bronze). Each time you do that quests you get a grade. When you do that same quest again, you get a new grade based on how well you did that time.
The primary reward system does have a method for 'trading up' where we allow you to choose whether you're going to get a random bronze medal quality class specific item or instead get a little more progress towards getting a silver item. So you can either cash out or turn your pennies into dollars, in a manner of speaking. As of now you can turn bronze into silver progress, and silver into gold, but you cannot turn gold into platinum. The best rewards must be earned by doing the hardest tasks, not grinding and saving up a lot of the easier ones.
Also as of now, a platinum is a platinum is a platinum, doesn't matter where you got it for it all counts the same. Numbers are being watched through playtest and iteration to see if that needs to have a slide based on group size but at the moment it doesn't feel like it does.
Promotions are the advancement system of Big Battles. We look at only the highest medal earned for each Big Battle quest and give you a certain amount of points to spend in a new tree related to the new mechanics and gameplay within Big Battle instances. A platinum medal gets you more points to spend than a bronze medal. Given that we only look at the highest earned, and not lifetime earn, doing the group spaces in addition to solo will provide more points available to specialize and improve.
