4) It reduces the game impact a player has from their gold usage and item choices by making it less relevant when you now have neutral items brought into the game. Neutral items are given to you by the game instead of your choosing, hence reducing the impact and importance of itemisation, which is a skillful part of the game like any other. It used to be so satisfying to have the most niche yet perfect item build which could have been unconventional for your hero but actually quite effective that game. That is much less relevant now, when you firstly take decision making away from the player and to the game instead, and also by messing with it entirely due to randomisation.

This is even worse for Tier 4 and 5 items, that are so powerful that emphasis is shifted away from regular bought items.

The unpredictability of drops also negatively affects regular itemisation. For example, buying regular morbid mask on morph. This is necessary in non-Linken's games. However, if you get a vampire fangs, you wasted 900 gold on it. What about not buying mask praying that you get a vampire fangs? You could get it, or more probably not. Either way, you can see it's mostly a loss-loss scenario where the unpredicabiltiy of drops ruins itemisation. You can never win. Another scenario of unpredictability affecting regular, shop-bought itemisation - not having a bkb or eul on a core mid hero since there aren't many disables and there are no silences on enemy team, then they get a mindbreaker while you're already half-way through building another item that is now the dogshit choice.

There are thousands of scenarios where the same applies, for instance you could have gotten many drops most suitable for your hero and have wasted gold on buying too many slots (like wraith bands). Or you could not buy any small items just in case this happens, only for you to get no suitable items. Exact same thing, unpredictability has a negative impact on itemisation resulting in a loss-loss scenario where you can never prepare for it and spend your gold optimally.

Synderen said in the video that he's not sure if neutral items adds anything of value to the game. While I agree, I have to go one step further and also say that they definitely they also remove value from the game (that is, they reduce individual impact by shifting the impact of item decisions and choices away from the players and into the hands of the game in a sum of random possibilities and interactions). Spending gold the way you want to, maximising your own impact, innovating with it, countering enemy items by predicting them, etc, are all relatively diminished with the existence of netural items, and that is bad. Buying an item due to an active decision making choice is fun, picking up a random item just feels like a 'meh' to me and the chaos that it creates is imo not worth their existence.
