The issue is that it isn't 80%, the issue is that it shows you it's 80% but try reloading ten times and see how many of those ten times you actually hit. I assure you, it's not even close to eight times out of ten. That is one of the issues.
This is one of my major complaints about the combat system and % chance to hit, it IS very frustrating!!!
As I understand it, 80% chance to hit does not actually mean you will definitely hit the target 8 times out of 10. It means you still have that 20% chance to NOT hit, and it is entirely possible to have an unlucky streak of dice landing in that exact 20% "miss" zone several times. (Sigh, this is usually where I give up on math, because my "math should be fair" logic and actual math probability does not make sense.)
the problem is, I believe, algorithmic in nature, i.e. the numbers are off because the AI isn't playing by the same rules as you the player are. In short, all these issues together are creating a combat system that is simply not fun to play.
This may well be the case, and if so, definitely needs tweaking so the AI rules are the same for both sides. Also, we are limited to level 4 but are the monsters higher level? I don't recall at the moment.
