There is not going to be seats for everybody who is travling on the flight. Do people expect about 200 seats at the gates. You could of moved down and watched for when the flight was boarding. I may sound blunt but it's fact.
Frankly? Yes. Waiting at a gate is not like going for a train or bus - the wait is longer (at least 30 minutes), and all users will want to be near to the gate for boarding, even with assigned seating on the aircraft. This is especially true if you are travelling with children are elderly or mobility impaired. You may be able to move quickly a long way to a gate; others are not. If the gates are designed for aircraft of 2-300 seats, then seating in the terminal near to the gate should reflect this. If it does not,then the design is faulty, and as heidleberg said above the airport authority should be ashamed, and not publicising it it expensive, unnecessary TV adverts as a world class terminal.
