I was having so much fun having to min-max weird builds in some games (like needing to sacrifice my DPS glasscannon's attack so they will withstand AoEs, lower the defense of the tanker so she has more speed to cast taunt even faster than rapid mobs) and I feel this is what's missing in most isekai.
Like, I remember I found really awesome in Hardcore Leveling Warrior how he was using high quality anti-magic armor from when he was max level and that was why he was seemingly immune to magic attacks. But when he went to fight a warrior, he switched full gear to the point it lowered his STR and the like to increase INT so he could fight like a mage, and further used numerical stats for an actual purpose to gauge his opponent's damage with the amount of magic barriers and the hit points each barrier could withstand.
I just find weird all those stories are obsessed with levels, ranks and values, often overbloating the protagonist's but they never do anything with that aside some DBZ powerlevel equivalent. There is a lot you can do with that including even making a protagonist being able to take multiple roles. But even when a guy has ALL skills his uses and fighting tends to be constant.

How is this one? Sounds like MGQ

To be fair most of the time anything you really want to murder with DOT tends to have super high resistance or immunity. It's usually unreliable or need a party to make up for min-maxing the necessary stats to land the ailments with consistency
