Whoever thought it was a bright idea to make Zombies knock you out in less than 9 hits is the worlds biggest moron, it is impossible to Melee fight 2 zomibies let alone 1 now.

Every update there is always some changes that are very unnecessary and are not even related to what is actually needing fixed, quit expecting everyone to come to the Feedback Website to report a feature change they don't like or some bug fix, include a in-game report screen and i will guarantee more reports/feedback instead of some external use.
