I have seen dodge counters - mainly in heavens palace
I believe this occurs when the stats are high enough to trigger a dodge and a block.

I have also seen counters with neither a dodge or a block registered. This mainly occurs in Heroic Realms with the main boss such as Baron Fuego

I am not sure if these odd ball occurrences are because of manipulated stats in Heavens Palace and Heroic Realms or if you can eventually with runes and Saintings achieve these results in a normal PvP situation

Or if these odd ball occurrences I have witness multiple times are merely the results of glitches
