I love the idea:)
Certainly they'll have to implement some limitations, like..after filling up the summoning gauge the free company has only 2 days to summon it or "the power will fade" and some other free company can get it and start filling up THEIR summoning gauge.
Obviously it shouldn't be possible to use the power of a Primal God against himself or another one like Garuda..or if it works, it should only deal a little bit of damage, not the "complete wipe" dmg it does to other monsters and players.
Maybe sometimes I'd be pissed of at people who use this function, but really, it makes the game just that much more exciting :D
