Same GC Ifrit killers gets better reward

[Malakhim]

So after doing this, it seems the only reward you get is the first time you beat it. you get like 2k exp and some seals. SOOOOO what is so great about that??? why both mentioning that u get a greater reward, unless something special happens only if u have all members of the same company in the party?????

"What's so great about that?"

You get more seals. That's pretty cool, and fosters inter-company activity, while not being enough of a turn-off for those who want to be in the company of their preference.
