Spider Minion targeting

The spiders from arakaalis fang will target basically ANYTHING before the stuff i actually want dead.
Breach? Run straight for the continuously spawning trash mobs which gived nothing instead of the breach boss standing RIGHT ON TOP OF ME
Kosis? Stand next to him while he channels and they will still run to the random one and a half screens away.

Why not give them a basic priority in order of mob rarity? Or how about giving players a simple button for marching orders which does nothing except cause them to attack the target i point at. No predator support, that thing takes up an additional socket and an additional hotkey. Just let me press caret ^ or something to "mark" an enemy for minion focus.
