The golem, especially with the paragon board for the golem, is basically a monster. I did use him though if I really needed another tank because warriors got wiped fast XD IDK if these things are intentional but IMO they make the weak necromancer minions feel even worse.

There is no ability to focus your minions and they will spread out and focus what they want which can be annoying against a monsters summons when I want to kill the monster summoning them. I’ve noticed my skeleton mages will not fight right away on the edge of my screen even though I’m attacking, or my other minions are fighting.

I’ve noticed my minions not focusing my target and will sometimes focus an immune target in events and such, forcing me to move a certain direction. I’ve noticed the Golem will focus one target even though you’ve activated its skill near or on a specific target. It also happens on things that you need to destroy for events/quest, if it’s big enough the golem AI is just so bad it does circles, sometimes not even completing his skill.

I’ve noticed that my Golem will often run around in circles of a big target if I click the active skill on them.
