I play path of damned difficulty and have just got the fifth party member. I feel like the biggest problem is lack of accuracy: every swing, ability or spell has a very high rate to miss or graze, and this often leads to a wipe or a knock out. Most of my characters have accuracy around 25-45, however I have seen mobs with all 4 defense at around 80ish, even with all buffs from food, rest and spells on it's very hard to actually carry out a strategy which relies on a certain hit rate of abilities. I think there must be a certain accuracy threshold that you have to reach, otherwise your team build won't be legit.
If I get it right, perception is the main source of accuracy, so why isn't it the most important attribute for most classes? Why would a DPS need might if 1 out of 2 hits is missing? And I read an article saying perception is mainly for defense, why is that?

The reason perception is not that important, is that it only grants +1 to accuracy per point above 10. Whether your characters sport 30 or 35 accuracy (assuming 15 perception) doesn't make much of a difference, the 15% dmg increase from might or 15% atk speed increase from dex have a far bigger impact.
You are correct though, that accuracy is the biggest problem on higher difficulties, however perception is not the way to get it. You still should have a character with very high perception (18+) to detect secrets and traps. (note: this only applies to PoE 2, in the first game, mechanics skill is used to detect secrets and traps.)
The wiki has a comprehensive list of accuracy sources. Here are some tips:
Finally, reducing the opponents defenses is also very important: ciphers are very good at that. List of afflictions. Prone, blind, stuck, weakened, stunned, paralyzed, charmed are all available pretty early and debuff the enemy significantly.
