I 100% agree with his comment on the Perks being non-unique, and just skill-boosters.
To me, and I have said this a few times on the this board, the BIGGEST flaw in FO4 is the new SPECIAL system and perks.
I know a lot will disagree with me, and I do appreciate the change away from the skill system to just perks (in that sense I guess I disagree with the video poster) since the skills had effects taking place at 25-point increments, but I would really like to see Bethesda create a system where the traditional skill-system is governed by your SPECIAL stats or left for the equipment being used (IE no extra damage skills for guns), and then create a perk-based system which is very situational, and as the video states, allows you to 'break' the game by allowing you to approach a quest differently.
For example; it would be much better in my eyes if the perk Gunslinger, rather than giving you a damage booster to handguns, gave you skills like:
Rank 1 - Can target enemy guns in VATS to disarm them, and adds a small chance outside of VATS to do so.
Rank 2 - Guns you disarm will also deal explosive damage to the enemy.
Rank 3 - Can target grenades mid-air or in the hands of the enemy to deal significant damage.
etc. etc.
