Adding a harder difficulty mode that just, again, increases enemy stats would be counter-productive. All it would accomplish would be to force the player to use the most OP nonsensical MC builds and resort to Illithid Powers, whether it makes roleplay sense or not. It would just limit your options. I wouldn't touch such a mode.
I'm already really annoyed with tactician. There's nothing tactical about it. You can go all-in in every single encounter with reckless abandon. Enemies just have more HP, an arbitrary attack bonus, and they focus fire Gale more.
Having a Long Rest cost double food means nothing. And if you actually run out of supplies, which is impossible, it would just be an inconvenience to go get more. Camp Supplies is not a real game mechanic and I'm flabbergasted the devs are completely unable to make Long Rest work in any meaningful way. The entire 5e system is designed around that. They should make an effort.
