i dont understand one thing - Regalzeva already killed Great Red strongest being in this universe, has brother with similar level of power, they has 3 servants with power comparable with GR and for what they will wait 30 years??? They will wait time for their enemies to become more powerful??? In war theory when you send unexpeted and strong attack and succeeded (who will say that easy defeating Great Red was expected) you has to go with full strength against enemy territory to utilize succes. Its even more necessary when enemy dont have as strong forces as you.
