>>23383438You two anons are talking about different things. So we need to ask for clarification.
1. Are you asking why all these mobile suits have hard points to begin with?
- A decision was made early on to keep the hard points. No one knows exactly why. Maybe it was an artistic decision by the Director.
2. Or are you asking why they can't remove the hard points later on once the anime is in production?
Once production already starts, too many wheels are in motion to make changes. That's why planning is so important. Schedules are extremely tight once anime enters into production and the studio signs contracts.
Bandai reserves timeslots with TV stations for their anime. This is very expensive. And even a small delay in making animation can have a "butterfly effect" down the production pipeline, and delay an episode by a few days. This is unacceptable because TV stations will charge absurdly *gargantuan* fines for any delays and not following signed contract.
And that's not even factoring in paying overtime to staff members to make changes. Each anime has a budget. And the allocated budget may not allow for overtime pay.
If you read old stories, Gundam Seed Destiny's production suffered so many delays and setbacks. It got so bad that staff members were literally driving to the TV station to deliver that week's episode tape only 45 minutes before it was supposed to air on TV. And the staff were only delivering a filler recap episode because the animation team had fallen behind schedule for the battle scenes.
------------
For the DVD or Bluray releases, changes are much easier. It doesn't cost nearly as much since you aren't limited by a tight TV schedule. A lot of animation fixes were done this way.
