IMO, it's probably the least interesting Legion story till now. The only parts that are genuinely good are the bits with world-building from the perspective of top-tier faction and power system theory-crafting. The rest is just too similar to Soverick's story to be entertaining.
These choices are interesting, for example if in the great fusion he unites all divine abilities to create his own, wouldn't he have a divine ability that can grow indefinitely? Because of the dragon heart, the diamond that becomes strong by absorbing light and also because of the 7 legion.
