I'd say that around the T5 to T6 transition I stopped looking at my total value towards uncrushable and worrying about block rating period. As Lore said just based on the fact that the gear gets better all around it can make you lazy about such things. For example for Bloodboil I use a set of gear I have labeled "OT Threat". It maximizes spell damage and uses the 4 piece T6 bonus to consecrate. I give up a lot of avoidance in this set but magically I'm still well above 102.4% combined anti crush stats just due to the higher average Ilvl of my gear.
Short answer you are not crazy. As you keep gaining access to higher levels of items you begin to stop looking at the items +/- crush value and more at it in terms of +/- stam, BV, avoidance, threat, and so on.
