^That quote was an advice from a DMM player long before the game was even released and was still in pre-registration phase.Join a really active Union, don't be stupid and stick with inactives or low population ones. When Union event comes around, you will want to stab your ownself to death for being in a shitty Union.

What he said is pretty much true because if you only get x300 Holy Soul points per Union event for max rewards (including individual).
The Morgan series needs - 900 HSP
Shingen series needs - 1200 HSP
= 2100 HSP
There are 7 element (Light, Dark, Water, Thunder, Wind, Fire, Illusion) Union events. Meaning 7x300 = 2100 HSP exactly.
Meaning if you even slightly mess up in any of those Union events my not maxing out your HSP rewards, there goes your chance of getting those two Heroic Souls.
