Now, I have to say I think the three hit on armour was the best version. I'm almost exclusively a melee player, so there's no bias here, but it was a little too easy before. Not as silly as the 1 hit to everyone mode in the first demo, but a nice balance. Before, there always seemed like 2 melee players per team, then it went to practically zero.
If they have reduced it again, hey, it makes my life easier, but as I was already getting around 20 kills a game just with fists anyway, I really don't think it needs toning down, and I kind of liked being one of the only players still doing it.
