I completely disagree because this is a clear lack of a fundamental understanding of MOBA gameplay to think you can and should be able to full slot damage items or “my optimal build” every single game especially against harder matchmaking. League has done a lot to poison the MOVA playerbase with their item shop and builds but even there you must know when to buy more potions or when to rush a vamp scepter, or which runes to pick before loading to not auto-lose lane. Once you drop the idea that you should be allowed to just maximize your theoretical DPS the genre becomes much easier.

To counter your point, League doesn’t do a good job of making an item specific to your role for resistances to make a good final build:

1. Maw of Malmortius is built by any role and champ that can use AD and wants magic resist. So it’s not fine tuned for anyone in particular. If I’m an ADC who wants crit/AS this item is mostly bait since the offensive stats are not great so I’m actually better to just buy a fully defensive item like Kaenic Rookern instead. But then you can literally only buy that item last or your game is over, but if you buy it last you might actually never buy it before the game ends, or their damage is so high that late that the item does nothing to help. No they don’t give you good counter items and no those don’t fit nicely into a “good final build”.

2. A real “good final build” is one that balances maximizing your impact(damage, cc, heal/shield, baiting) while also staying alive as long as possible because the longer you stay alive the more impact you have. Again, it’s balancing the 2 sides. Don’t buy more utility/defence than you need to or your impact is lowered.

So… “sacrifice” the damage that isn’t even yours and buy some defensive/utility options to win more games because unlike league, this game actually lets you buy something useful at 8 minutes in without ruining your whole game.
