Noticeable Crits/Block/Dodge

It would be great to have a system in place for providing information about crits done, blocks, dodges and soforth to enemies, and the player.
A subtle hint would be fine, a small sound clue that is slightly different from the normal hit sound, or a small light/blood effect on the mob maybe, that is different from the non-crit hit.
This would give a much needed information how much I block, how much I crit etc.
Of course the effect itself can have a cd for the dodge or block, so it doesn't become intrusive, but it would feel so good to know that I blocked a big hit, and that's why I'm alive.
If we hear a crit sound/see the crit effect when dying that would also provide useful information why a white mob oneshoted me.
These clues could be really subtle, nothing over the top, so the basic feel of the game doesn't change.
Just think about it. :)
