New reward: ascended dungeon gear
Suggestion: New tier of rewards for dungeons introducing new styles of weapons and armor, at ascended level. In order to preserve the philosophy that ascended gear comes from Fractals, laurels, or Crafting only, the means of purchasing this gear will require an exorbitant amount of tokens particular to the dungeon, plus one generic token that can be bought with (an exorbitant amount of) fractal tokens. This generic token will also drop at higher levels of fractal difficulty (31+). This gear and generic token will be account bound.
Additionally, round out Fractals skin rewards with armor skins, available only as drops (like the current weapons).
Optional addition: add a means of tracking completion of all dungeon paths (another token per path, possibly), one time per day. When all dungeon paths in a dungeon have been finished, completion will grant an additional chest which can contain a rare (skewed towards regional skins), (RARELY) an appropriate lodestone, or (RARELY) a random piece of dungeon gear. Because this is GW2, also include masterwork trash as filler.
Pros: New dungeon rewards revitalize dungeon grind. Interest in Fractals sparked. Rewards do not require gold or gems to purchase. Ownership signifies skill since the items cannot be bought. Can be worked toward an eventual payout even if the RNG system never graces the player with the appropriate drop. Drop rates should be small enough to ease into the game.
Cons: Seriously reinforced grind. Complaints that rewards aren’t sellable (which is counter to fractal/ascended gear philosophy, but whatever). Lower skilled players in fractals will incite complaints about noobs. Lots of work to create new resources without clear benefit to ANet. All players will have complete set of CoF skins within 2 weeks of instantiation (proliferation of CoF tokens).
You can get Ascended gear as a drop, just like from World Bosses, but it is a very rare drop. You can even get some to drop in WvW, so this is no big deal.
