OK, so I watched this out of interest and I must say, he's a douche - I couldn't watch the full thing.
His initial comparison is to Left for Dead. L4D isn't a tactical shooter, its a run and gun without strat or hesitation. He seems to be complating for the sake of complaining, certainly doesn't understand what this game is trying to achieve. WWZ is a cross between Dead Island and Division. You've got similar gunplay, character movement and item interaction as you do in Division. His rant about picking up item is just stupid. As for the skill trees, that's exactly how RPGs are supposed to work. Same for Destiny 2 and Division 1/2, the investment into your skill tree/abilities/talents makes you a more formidible player.
Given the level of configuration you have against your weapons and classes, I'd say this reaffirms the games position within the Division type genre. I love how little mods/changes to gear/weapons/classes can have a positive/negative impact.
All in all, he's playing the wrong game if he's after another L4D game, this is not it.
