Faith is the most precious treasure for the vast majority of deities; no deity would trade this for anything. The only way to gain faith is to seize it by force.
Sylvanas was even willing to grant Laila Lesser God status, yet she only gave her a hundred Druids, leaving the rest to be developed slowly on her own.
This shows just how precious believers are.
To obtain faith, one must either turn the faithless into believers or directly snatch the followers of other deities.
Such actions would strike right at the arteries of deities, leading to very sharp conflicts.
Amberser really didn't want any trouble with the deities, not even the weakest among them.
But sometimes, there's no choice, if only Rowetta hadn't come with the intention of freeloading, Amberser would have already reached a cooperation with the Goddess, and wouldn't have offended the Goddesses of the Evil Camp along the way.
And this time, he wouldn't offend any deity anymore.
