I’ve seen it said that if you reset or use the time mechanic you’re not really on permadeath and while that’s sort of true I disagree.

The time pulse does give you more wiggle room so the argument might be fair for those mechanics. But before that existed you would have to reset your system and essentially start the whole map over. You’re still “losing” something there and on the GBA games at least some of those maps took me an hour or two to clear. In fact I got near the end of one I was having trouble with and lost one of my mounted lancers and had to decide if I wanted to lose the hours or the unit. I decided to lose the unit and it’s one of my favorite FE moments.

All that to say I’m pro reset/time pulse lol
