Putting your useful information more towards the center of the screen/in an easy to see spot WILL increase your performance, whether you think you are performing at a top level or not. What happens when you look up at your buffs and try to find the intel buff? Oh you finally found out. But now your dead because you didn't see the void zone on the ground and our addons aren't updating to warn you because this is progression.
I highly encourage to get a UI/edit your UI to put the useful information closer to the center/in an easy to see spot without anything else around it.
Here is my UI. My bottom left area above my chat has my NeedToKnow, and the bars on the right side are my Int buffs. I don't even have to actively look at it, I can see how many bars there are and know when to refresh my dots for the full effect. The rest of my information is located in the center of my screen. Short of cds, I don't even need my bars on the screen.
