I haven't bought a DLC in a LONG time. These days I just sub up for ESO Plus for a month if I feel like doing some newer quest content, and play through the zone before my sub runs out. How could ZoS make more money off me, as well as making me happier with the Store options?...
Simple. If a player has the Grand Adventurer achievement (or similar) for a DLC zone, slash the crown price of that DLC.
For example, I've completed every single quest in Southern Elsweyr even though I don't own the Dragonhold DLC, so there's not much point buying that DLC at full price. But if the cost were 1/4, or even 1/2 the standard cost, I'd definitely consider purchasing it just for the sake of owning it.
Thoughts?...
