If you don't understand and just dismiss the fact that you can play the nightfall/weekly then it's obvious you haven't thought it through much. Making assumptions and baseless conclusions. You will not get a refund. You paid $17.50 for the expansion (not $20) $17.50/$20 does not have the same value of say 5-10 years ago. You can't compare what content is worth based on what you might have paid for something else in the past. But, if you really want to understand, $20 of today's money is worth about $10 not too long ago. Lastly, if you don't like it, don't play it. Learn your lesson and never pre-order anything ever again. This will solve your problem, not bitching and complaining on a forum.
