Skiizt, if you need help, start your own thread (you obvisously do). It has NOTHNG to do with fluff, and if you think critnukes are fluff also, please consult the mage forums for some hard facts / parses.
Alot of raiding defilers are running with anything from 60 to 100% critheal chance, so yes it does make a huge difference.
The fact that it's been broken since RoK launch, is a complete joke seeing the number of pure cosmetic fixes and useless enhancements that SoE obviously had time to make.
Personally I don't raid that much, but I do alot of grouping / solo content, and occasionally the t8 contested x2's. In trivial group content, you are lucky if your singletarget ward takes 1 hit from a yellow mob. So yes, we need everything fixed and critting as usual to maximize our healing potential.
I'm not asking for alot here, only that healing mechanics are fixed to work as usual...
