The easiest option i recon would be to remove the south fate in pyros, very easy to die up north and same with Hydatos, never done the one in pagos. I say its the easiest option going on the assumption they cant make the bots weave through the lvl 50 mobs up north, im sure they could code something for it but i don't have knowledge of coding so it might be an easy fix for them. ive tried killing them by rounding up mobs and dragging them over when they sync down, it worked a little bit but recently they started moving out of aoe and focusing the mobs then going back to the fate, before they just sat there and took a beating.

But i dont know how SE work or if they even read the forums so i dont have high hopes it gets fixed any time soon, unless someone has connections lol.
