Preach it sister!

Same here! I don't NEED it (just like any addon, it is useful but the normal UI is honestly fine), but it's awesome! I don't ever look at Omen anymore :D.

Threat-Plates also has a small "widget" in the form of a blue bar that hovers slightly above the health bar. It shows your relevant threat to your off-tank, is very useful as it can see who are set as tanks and then not worry about your threat on the mobs that are on your off-tank.

As a feral DPS/Tank all I can say is: Threat Plates was a godsend. It can be the difference between good threat distribution and an excellent one. And these days, with DPS doing ridiculous amounts of damage and still not knowing how to control their aggro, tanks have to use all the tools they can.

Install it, use it, love it.

I only picked TPTP up a couple of months ago, and from the first fight, I was amazed how I ever lived without it.

One small nitpick about the article:

Threat values that determine nameplate colors, size, and alpha are all based on comparisons to the threat of the leading person. So if you are tanking and someone is creeping up on you, that plate will be, say, green, right up to the second that the person pulls aggro, at which point it will turn red. So they're great for seeing (a) what you have aggro on, (b) what you don't have aggro on, and (c) what you're close to having aggro on but haven't actually peeled yet, but they can't show you (d) what you currently have aggro on but are about to lose.

AFAIK, anyway. If there's a way to do option d, someone please let me know.

Sleutel: I'm going off a memory and it's been a while since I set it up, but with TPTP there are a few settings you can play with to display how much threat you have compared to others on the top of the bar. I use the setting "Tug of War": if I'm tanking and have great threat on a target, there will be a "rope" from the middle of the bar to the right side (on the top). If the DPS start to pull aggro, the rope gradually gets tugged to the middle (it gets smaller). If I lose aggro, the rope will turn blue, and grow to the other side depending on how much threat the DPS has generated.

The title image and first image in the article seem to be using this setting.
