Melee needs a boost, three hits shall knock a player without any shield

I dont think so. The melee attack is fine right now imo. I've won many fist fight against those who already got a weapon and also fist vs fist early in the game.

It may happen that you win against an armed noob by fist fight or against an unarmed pro as well by fistfight, but in most cases that I have seen in my first 30+ rounds is that an armed player will take out non armed players. The loot is not as balanced as it shall be (countless empty rooms in high tier towns too), map is way smaller than in PUBG, player movement speed is ten times higer so games is tighter where you cannot really avoid face to face meeting with an armed guy vs your bare hands, one shot kill shotgun in her or his hand...
