There are many questions that have or will be raised regarding this change. We all know what the current process of the tournaments is, this may change with it becoming a fellowship help based feature (or not).
Yes in theory this should be an improvement to progressing farther on the check points. Will the new structure of rewards gained support this, only time will determine this.
As a courtesy to their players, it would be nice to have a refund of the knowledge points spent for this technology which going to become no longer needed. Just my opinion, I have my doubts based on responses from bug threads made over time and the lack of materials being refunded.
Blueprints - one step closer to solving this puzzle, however as has been mentioned, if this item is solely for use by magical building purchasers only, this could be a deterrent for increased tournament participation. If however, this is setup as an extremely rare reward and can be used on regular residences and workshops to get the same benefit as magical ones, this could truly be beneficial.
Fellowship Co-operation - every group strives to have the best possible combination of players for balance purposes with regards to goods. This allows the smooth flow of trading so that everyone can meet their goals. Prior to end game (if we ever see one), there will always be players at various levels of progress, this will also determine how far in a tournament they can participate. As a group everyone will have to understand this with patience in mind.
