Balance aside, there's definitely something strange going on with the dodge chances. I've had attacks that were reported as 100% hit rate miss multiple times. I've also seen 85% hit rate AOE melee skills miss 4 targets at the same time - which statistically should happen <1% of the time - and I've seen it happen multiple times (maybe it's only making a single hit check and applying it to all targets...? ).
I've had cases where using Mark Target onto some enemies, bringing the chance to hit up to 88 or 89%, shots fail two out of three times*.
*By that I mean three enemies. One 88 and two 89%, and I have a 100% chance to miss the 88 and an 89, and a 100% chance to hit the last 89%.
