Paragons isn't even hard on Normal. My guild isn't great at all and we went in there clueless, terrified of wiping for hours on the 7 billion different abilities and trying to understand it all - turns out we kill it in 3 pulls, with one guy dying to some colour coded ability thing. Haven't wiped since.
We still don't even know what half the abilities on Paragons do and the fight is such a joke it doesn't matter, LFR will just be literally tank n spank with a few flashy things that do nothing. Probably the hardest part of the fight will be getting a few people to switch to the amber block before it heals.
