I would like to suggest, that the Hall of Records Tab at the bottom of the screen under Blood Pacts be converted to an additional Upgrade Tab when all Blood Pacts have been signed (only when all have been signed) - this would be a better incentive to the higher level players to keep their interest. 

In that way players could Update two Blood Pacts at the same time.

The system should recognise when all have been signed and only Updates are required.

This would maintain interest in the game.
