file it under the category of lazy - it wouldn't be hard at all to fix it
I'm sorry, you know this how?
Refactoring an entire system that was at some point deprecated in favor of the "new" system is never an easy task . Not only does the original quest system content need to be integrated with the new system, but the old system then also needs to be removed. We also have to deal with any player who may currently be embarked upon a quest using the old system. Then everything needs to be thoroughly tested. These simply stated tasks translate into a tremendous amount of actual work for a relatively low payout.
