Just got my Paladin to 28 this morning and noticed something odd to compound the Judgement cooldowns, lol. Apparently, Judgement of Justice shows correctly on the mob. The other two Judgements are the only ones that do not.
Screenies attached
***EDIT*** Just so you know, at least for Paladin spells, commenting out line 1219 in nUI_Button.lua does enable the other Judgements to display debuff timers correctly. No clue what removing that does to other classes if anything though.
