I still cant see anything, since the actual action is happenin behind HUGE GOLD DICE.

I'm guessing that's for a good reason. Because if the huge gold die wasn't there, they'd have to do critical-hit animations for every single character and every single weapon in the game, or at least 500,000 animations.
That's ridiculous. They just need finishing moves that are the same for class/general weapon type/general spell type. In other words, critical hits for every single fire spell could reduce someone to a pile of ashes, ice spells could freeze and shatter an enemy etc. (that can still be looted, D&D actually has rules for this, but with all the other changes rule of cool can definitely prevail here), one or two finishers per large weapon (decapitate someone with great sword, battle axe, etc., all the same animation) since the key is impacting the enemy in a huge way not so much the animation itself from your character. You'd need like, 10-20 animations.
