You may be missing the point. They can't do it indefinitely. They can't do it every week. The limit has been around for about 3 years now.You are making it hard on the 100+ items issue do you? I do not have issue when you have a limit of 100 items and you are able to maintain the points. What we are discussing are those that have 100+ items before.
If they had 10,000 landing lamps before the change, how many times could they fly 500 flights in a week requiring landing lamps before they deplete their stock to below 100? Twenty times. That's it. Over 3 years, twenty times. Then they would be back on the same field as you and I where landing lamps are concerned.
