But more DLCs will be added. How many of them there will be in the future, the developers themselves do not know. The lack of new character levels will have a very bad effect on new locations.
Well, it is possible that big DLCs will come with an extra level or two. In the meantime, isn't it possible to focus on other rewards next to leveling up? Your characters can still get better by finding or buying better equipment, or by completing quests, or by discovering new areas. Besides, not being too reward focused could help you enjoy ther game more. The way the story develops should be interesting by itself, and can vary between playthroughs.
