We have added lots of new guides and builds for every Javelin and a a few more lore videos. More will be added in the coming week. The builds are on a separate page now and the next app update will have new shortcut buttons to access guides and builds.
We added several new guides and maps. Some of them are about farming the best items, Anthem's Loot Cave, Coins and maps for farming chests.* The newest guides are on top but we will reorganize the page very soon. *BioWare recently reduced the chance of finding high level loot in non-event chests.
