Pff, I don't know what people got against addons. I've never used a damage or threat meter other than to constructively tell people that they're doing something wrong.
Without meters, there's no way to tell who's pulling their weight or not and you will never know whether your class is balanced in the DPS department, compared to others. Yes, blah blah, there are other things than DPS - yes there is, but that's to be balanced on their own.
Seriously, either you ended up on the wrong stick of a bunch of meter jockeys (which probably means that you weren't doing what you should) or you just don't like numbers.
I love the statistics metagame. I want to be able to see both an post fight chart and a real time one.
Also, everyone knows that this UI is crap (that it's early game or not is irrelevant to the discussion), or you probably never configured one before. I want a wide array of UI features to choose from, and Bioware won't make them quick enough.
Can't do it fast enough? Take help from the community.
Stop with the addon hate, there is NOTHING that becomes less skilled because you're using an addon.
