[Spoilers C3E121] Why not send an endless army of divine servants against him?

I haven't followed C3 in a while now but I read the arc summaries and the plot for the finale. Sorry if this has been answered before, but why haven't the gods sent thousands, tens of thousands, a MILLION of solars, devils, demon, and whatever else from beyond the Divine Gate to destroy Ludinus, everyone associated with him, and all their plans?

Seems a much safer bet than leaving it to be mostly handled by a bunch of mortals on Exandria

And yeah you can say "well why wouldn't the gods send an invasion of their servants every time they want something to be done in Exandria?" and I wouldn't be able to answer you that other than saying "maybe logistical issues". But I feel like when the issue is as critical as their own annihilation, maybe it is worth it to send an army of divine servants that stretches to the horizon

So why not? Why not wipe out Ludinus and his lot in a much more assured and assertive way? Predathos would've never been released and they wouldn't have needed to diminish into mortals. Again, if an concrete reason as to why that can't happen was given at the table, sorry for missing it
