No need to be passive-aggressive about it. If you weren’t struggling or having issues in some respect, you wouldn’t have made this topic would you?
Your experience differs from mine then. If I walk up to an enemy or crowd of enemies with my pets out, they engage them immediately and while I’m at a distance 
.
Take a Skellies character as you’ve shown screenshots of your character with them, this is roughly the distance they start engaging for a typical crowd and I find that perfectly fine for standard gameplay:
This isn’t just for the Archers either. The basic Warriors charge into an enemy well in advance, it’s just harder to showcase that in a screenshot.
Beats me. I played this exact same character with Raise Skeletons from the moment I made the character to the moment in those screenshots and never had complaints with the way pets respond to enemies.
Aggro management (e.g. how often your pets keep the attention of any kind of enemy, Bosses especially) is something that all summoners struggle with as some skills your character casts to support your pets raises aggro to your player character immensely, Curse of Frailty being a well-known one. Bosses and rarely some common enemy groups (like Dranghouls in my experience) are also resistant to threat/aggo generation effects so are harder for your pets to keep occupied than others.
But like you said, it’s your suggestion. I just wanted to voice my experience on it and believe I’ve done plenty.
