Hi everyone. This is my first post, and I apologize if I'm ignorant of common knowledge on this forum. I got into Fire Emblem just last year, and Path of Radiance is honestly the first RPG I've ever played. I finished a playthrough on easy mode through both PoR and Radiant Dawn, and wanted to do another run on a harder difficulty setting. I've been looking through this forum, and it appears my efficiency at playing the game is drastically below par (e.g. I don't finish a chapter on BEXP pace, I often place characters in situations that result in their deaths multiple times, my characters are often underleveled, etc). I know this a rather difficult question to answer, given how broad it is, but do you guys have any tips for how to play the game better? I know a lot of it will obviously come from experience, but I was wondering if there were some important fundamental concepts I had to get down to stop running around like an idiot.
I have some basic knowledge, such as the weapon triangle, attacking outside of range then inside it, but I feel like I'm also letting many mechanics wash down the drain, such as shoving (is it that useful?), rescue, Order/Direct, etc. Again, I apologize for asking such a broad question, but any help would be appreciated.
