Look, I get that it sucks that your thralls don’t work. But if you’re going to use them in purges out of some ‘principle’ then you’re simply choosing to bang your head against the wall. In your situation I wouldn’t summon a purge to a base with thralls present. But either move them or create a base target without them present.
If I had a tank that didn’t have an engine, I wouldn’t be asking to have its armor or weaponry upgraded. And I sure as hell wouldn’t be putting it in the front lines.
My point is when thralls work, they work. I don’t understand why players who have thralls that don’t work continue to bring them out just to lose them rather than stow them away until that issue is fixed. Giving them 1,000,000,000hp and 10x that amount in armor isn’t going to make them anymore useful. Giving them enough damage so that they oneshot every mob on the map on all 15,000 servers and as many instances of singleplayer being played at that moment isn’t going to improve them if they aren’t attacking.
Being as players need to get to level 10 to even get a thrall and thus there is the whole process of getting the thrall without one. There is content in the game that can be done without them until they get fixed. I would recommend everyone to simply do the content they can without thralls until they are fixed.
Sure it sucks your preferred playstyle is broken. But I don’t see how playing to be frustrated is any fun in the mean time. If losing thralls is fun, by all means have at it. I won’t judge.
