I LOOOOOVE NUMBERS! I make the font bigger on my UI for heals, just so I can appear more awesome!
Well, really. I don't mind the number-munchers, as long as they don't throw the numbers at me in dungeons (lvl 15-90 normal dungeons).. keep them away from there, I do no hesitate reporting people for spam. But within Heroics or Raids, I see a use for it. LFR for example, has a good use for it as some people still use LFR as a shopping cart and lets other people push the cart.
For normal+ raids, well, you are expected to trust your raiders a bit, but good to keep the numbers going to see where you can advance, do changes and more.
For Heroics (Dungeons), please.. just.. share them pr. boss fight.. no more, no less.. not on trash.. or because you feel like it.
But hey, we all have our opinions to share!
FOMO: "Fear Of Missing Out", also commonly known as people with a mental issue of managing time and activities, many expecting others to fit into their schedule so they don't miss out on things to come. If FOMO becomes a problem for you, do seek help, it can be a very unhealthy lifestyle..
So we're right back to meters. /boggle

Meters give you a way to see what the player might be doing wrong. I'm not here to publicly shame someone for bad performance. If it's a regular then the mature thing is to point them to resources that help them improve. Suggest addons or the removal of poor addons.
For example we had a trial shadow priest in ToT. After the second raid we brought up that his dps was extremely low for his ilevel. He gave us some weird answers that didn't make sense. So I ran him through askmrrobot and all his crap was wrong. Not to mention he hadn't enchanted 3 items for over 2 weeks. When we asked him to verify his rotation it was completely wrong. We gave him one more raid and he opted not to change so we moved on.
With no meters a person like could be extremely lazy and be hindering progression without anyone noticing. I really hope people aren't referring to 5 mans, scenarios, etc. Because getting upset over meters there is pretty lame. If you don't like carrying a small group, queue with friends.
Yes, there are different difficulty modes, but within those modes majority of the time the conditions for success are pretty much fixed. If boss does A, you do B or you fail. There is no failing to do B and maybe get a lesser reward and rarely can you "recover" from failing to do B.
Raiding is all about getting a pattern down. A fixed rigid pattern.
