Since the update to all spider attacks and their AI, I was wondering if it translated to the tamed spiders too;
I noticed all tamed spiders only perform one of the new attacks added in for the spiders, which is where they back up and shoot a web ball at the target:
However, the wild spiders (both regular and widows) have a wider arrange of different attacks that the pet variants don’t do.
For the regular spiders:
and for the widow spiders:
On top of this, tamed spiders don’t attempt to strafe left & right like wild spiders do.
The last thing I want to add that really isn’t bug related and more of a suggestion, is that the higher tier variants of spiders have no stagger resistance, which makes it hard for them to get almost any attacks in.
could perhaps the higher tier spiders get some sweet, sweet resistance possibly 
This was all done on testlive singleplayer, no mods.
