Guild Wars 2

Create a new tier of loot just above ascended that is drop only, weighted toward defensive stats and having a high drop rate. At the beginning of a season, all gear of this tier generated during the previous season will be turned into exotic.

This has two big effects. First it creates a slot machine loot approach in WvW that will keep even hard core players looking for that next killer item to drop for their build. Second on the reset it allows new players to start at the beginning of seasons on a more even footing.

I would also have the game constantly increasing the drop rate for this tier of items on a player until they get an item then it would reset back to its base percentage. Leave for a few days, come back in and bam almost immediately a good item drop. Play for an hour no drop, the chance of a good drop would just keep going up until you get one.

Items could not be traded or sold and only destroyed for crafting materials.
