I think people whine too much about this and possible gear wrong.. maybe the gearing is more towards DET and DH...

Also for any given window it is all about skipping mechanics... if lower crit rate does this, then it also get more difficult to skip a mechanic... skipping mechanics in raids = bad and lowers the players skill of being able to actually deal with these mechanics...

Everyone that play this game know that every boss Savage as none Savage all run on a scripted run and if you can pass the time limits you will entirely skip certain mechanics.

Let it stay as it is, if it mean it is more difficult so be it, if you need the next tier to beat the previous.. so be it.

Also main stat is STR, DEX whichever stat that adds to your main attributes.. CRT, DET, DH,TNC, SPD, PT, SPS is all counted as secondary stats.. and most of them you can only raise the percentage of whichever thing by a couple of points by adding to.
