It doesn't. Increase your Ignore Trash Mobs value if you feel like it's attacking too much trash.
That doesn't work for DMO though. DMO doesn't care if there's 2000 mobs in a 100 radius the only thing it's ever going to kill is those that get hit by Arcane Orbit. I have been running with 20 radius for almost two weeks and it ran really decent and suddenly this causes Elites to be skipped? It never skipped elites before so what changed? My Flashfire Wizard has never skipped an elite and it's set to 15/10 so even though this fix "works" for some it's clearly not normal. Something happened between updates to make the bot skip Elites and it should be fixed. Even if it's a work around fix you still have to admit the bot used to have no problem with this and only recently has this appeared. So changing settings in response to a bug doesn't seem intuitive. It's just a band aid and what happens if that breaks in the next version? It would be appreciated if this issue was fixed rather than relying on band aid fixes that just mess up other peoples builds.
Here's what I had before switching settings:

To add onto that we used to run 8/20 for Mobs/Radius so just scaling linear to we can't even double both values with the current bot. Trash pack size can only go to 15 so if you could increase that as well that would be nice.
