Please stop being dumb and wasting a GCD every 10 seconds to put up light to make your healing look higher. First off, healing meters mean shit and the only thing you should look at them for is to make sure someone doesn't completely suck. If you're last by a huge margin, something is wrong. But if the job gets done it doesn't matter who is first or last.
I can't tell you how many times I see holy paladins judging light every 10 seconds to make sure theirs is up as much as possible to get those extra heals. That's 6 GCD you waste every minute when you should only be wasting one. Judge light all you want but watch your JoTP debuff and let the Ret paladin or Prot paladin who uses judgment in their rotation keep light up.
If you're the only paladin i can understand that, or hell 2, one can do light and wisdom but in a 25m raid where there are typically 4 paladins, stop.
If you're guilty of this, don't get mad...just learn to play and stop being dumb wasting your GCD's so you can flex your epeen for getting the most healing. It doesn't matter, save your GCD and stop being dumb!
