Purges - Recode to drop like meterors or triggered by players?

It’s so frustrating to be able to sustain purge bar, and I play ALOT. I seriously have to play basically every day for a week and grind the Red Mother and other bosses in the undead city to get the purge to trigger. Please find a fix, its been too long for this to go on since launch. Can’t you find a way to let players trigger it automatically themselves once in a week on their own bases? Alternatively, can you add a few drop points , perhaps one in jungle, desert, and northlands were a purge will drop say every 6 hours, like how meteors drop every hour or so up north?

That is why Purgementer should grow, not otherwise, for it is only dynamic end-game content.

Also, I think I know the game, where a purge-like undead were dropped on meteors periodically. I switched from it to Conan Exiles, because I heard about Purges.
