I believe that the High-Tier Longinus are defined as such by their potential in the base form. Just look at the 4 High-Tier Longinus: (True Longinus, Zenith Tempest, Annihilation Maker and Dimension Lost) All have immense potential even in their base form. The Mid-Tier Longinus (Boosted Gear and Divine Dividing) may even be more powerful in their final forms, but for their possessors to fight on an equal footing with others they need at least Balance Breaker.
