Technically the answer is no. HOWEVER, it does work exactly how you want it to. The triggered version does not cause you to stop and directly cast the ability. While you are moving and channelling warpath, Devouring Orb does automatically trigger and your Warpath is not interrupted. It even works for little hops like Void Cleave. Just to be clear though, it is required to be on your bar. Any ability which requires cooldown tracking is required to be on your bar to track cooldowns.

Yes but not a lot. Enemy AI frequently targets the closest thing. A larger minion is closer to more things and will be targeted more. It also blocks non-piercing projectiles better.

The second big picture in the top post here shows the patch notes date. It doesn’t say it in text form so it wouldn’t show up in a search for April 11 if you checked that way. I also did confirm it from the stream in discord yesterday but there I just said “…on the 11th” so a similar search also wouldn’t pick it up.

If you zoom out and click on the region, I think it zooms to the town for that region.

The reason that it being meta defining would be an issue is that it would create a burden of optimal play that would force players to take non-intuitive and tedious actions that aren’t fun. Frequently taking the time to switch your build completely like that to do content more efficiently is not something that we want to promote.
