AmunSet way to totally derail a thread on the first post. This has nothing to do with nerfing thralls and everything to do with expecting funcom to do a crappy job trying to copy soul mask thralls.
And how long have you been playing funcom games 
Two things to expect from funcom updates, more breaks then fixes, anything new is going to be borked and need a hot fix, and thralls /pets are forever getting nerfed one way or another.
I think it should be based on thrall level + tool level.
I remember in a dev vid a while back they had alluded to giving thralls the golem harvesting abilities. Have been looking forward to it because I think golems are janky, noisy, and a waste of materials considering some can’t handle showbills. Hell a salamander can take out a golem simply because a golem targets it’s standing opponents chest, salamanders don’t stand.
Maybe it’s me but I consider thralls expendable. I hate losing them, especially named bearers. But if one of my thralls makes it to 20th level I retire them, they deserve it.
For me, I’m the fighter, the thrall is the side kick. They are there as a distraction while I heal up, or the bearer of my loot.
But it would be so nice if set thralls could earn XP. Wouldn’t it be nice if you didn’t have to level all your thralls for your purge base and just running purges leveled them.
But, funcom. Even though they may try to implement it; and has already been done in a mod, doesn’t mean it will work any better then, oh, the new bench UI.
Supposedly they way things will wortk in the future you will have to place bench thralls in world; like the bar tender, where you can dress them; I sense incoming waifu costumes. I have no doubt they will add a bench like is in the mods, to customize your thralls.
That way instead of have to spend a bunch of time collecting thralls with a very specific look; say very buxom and blond, to hang in the 2 dozen gibbets you’ve hung around your open to the world maproom; oh yes I am judging you, you can just augment, and bleach.
Thrall limit is 65 for an individual, hundred if you make a clan full of alts.
They could make bosses fight smart enough they can’t be beaten. And it’s not so much time as memory space and computational speed.
8 years ago i was fortunate enough to be on a forum run by someone that was well known in AI at the time. They had a chat bot set up then that took me 15 minutes of chatting with to realized it was AI. Imagine what an AI boss could do now.
Odd thing was, it was a Poser forum. Why some one that was a genius at AI was running a Poser forum I have no clue. Poser is an actual; and the first, digital Barbie app. You dress the figure, POSE the figure, and render your book cover art.
How smart your game AI is dependent on how much space you allocate to it. I’m sure funcom devs have some hard set limits to AI because of it.
