Wow, you weren’t kidding on your achievement drive - impressive record. I’ve historically been a PC gamer, but have platinumed most of the playstation games I’ve played, like Dark Souls, the ps3 Demon’s Souls, the Uncharted games, etc. - I haven’t really played many games on the Xbox other than the Mass Effect series and, as an additional playthrough, Oblivion, and the ones I have played tend to be ones with significant multiplayer components so I don’t even really try to max out achievements, like Gears of War 1-5 and Halo 4. I really don’t like multiplayer shooters on consoles, although I have liked Gears multiplayer horde, and the similar Mass Effect 3 multiplayer. I played through Gears 4 multiplayer and a couple of acts in Gears 5 and didn’t even pop a few related achievements, bah.
Anyway, on the Gears Tactics Act 3-Mission 8 missions on my insane-jacked run, and have enjoyed it. The beginning of the Insane campaign actually felt the most difficult, although it’s still easy to have to restart missions since giving anyone a clear shot at your guys is instant death. But I love really digging into a game’s systems and getting to really know them, and considering abilities that might otherwise be ignored, etc.
Jack really helps a lot though, and the more powerful he gets the more he can help - you can just keep him invisible and blocking a control point in the control missions, for instance, and use all your guys to protect the other control point until you’ve drained it. That said, there are some stupid control side-missions on Insane, like the 2 person control mission in the 3-2 side mission. That one and the 3-8 side mission where you only get 2 AP per guy just seemed annoying so I avoided them.
