Why does the game tell me that I have 18,5% dr from Elites when I have a single node that gives me 19,5% sourrounded by three other nodes which reduce my damage from elites. I have even more from gear and a few nodes as well, so what is happening?

Theres so much wrong with this crap (Attack Power), seriously...

Thats why I thought too.....

they have trouble even calculating 40% of 1000 man. i'd venture to say any stat you see displayed anywhere in this game, take it with a grain of salt

Probably true yeah No idea how they can mess this up, but ok
