Just wanna chime in that I think it's pretty lame to demand people add more add ons to their game to deal with something that, for 75% of the expansion, wasn't necessary.
I've been tab targeting orbs all expansion long without an issue, and now it's an issue. Because? Reasons? Was this a necessary change at this point in the expansion? Were people abusing the tab targeting of explosives? This fix just makes it harder for no reason, and forces me to download nameplate addons I don't want. More weak auras to enlarge those that I don't want. And on top of all that, I now have to click to target orbs. Which I don't want. I'm not a clicker. I'm using my mouse for other things, and stopping what I'm doing with it to click on orbs every 10 seconds is detracting from my ability to play. This was not a problem when I could easily target orbs by standing in front of them and pressing tab. All things I could quickly do with my left hand to leave my right free to do other actions.
No. This is a stupid change. If that's how orbs were in Legion or how they wanted orbs to be in BFA, then that's how orbs should've been from the start of BFA. We're 75% through and most of us have an in-place system for dealing with orbs that we shouldn't have to change this late into an expansion because some idiots at Blizzard either broke it or made this undocumented change.
