I hardly look at the percentage score for any validation in my hits. I only look to make sure I'm situated correctly for backstabs and high ground advantages, and likewise to check my disadvantages.
And like 1var said, no need to show actually dice animations and cause the pace of battle to slow down. Just show me my darn dice so I can rage properly at seeing my crappy dice rolls haha. Just seeing the "miss" text is so underwhelming and lacking in depth of what really happened behind the screen. Just present me the dice and I'll accept the heart of the dice and attack results for what they are, and happily ready myself for the next move.
Come on Larian! Give us the visual goods!
