Just beat the game last night on Hard difficulty. While it definitely wasn't an easy Fire Emblem game (the last few chapters especially were pretty tricky), I had a few characters that were just a bit too overpowered (Donell, his son, and myself to a lesser extent) for it to seem like a real hardcore challenge. And while I would like to get even deeper into the team building and reclassing systems on a subsequent playthrough, I don't feel like the game gives too much of an incentive to do so, considering I have already beaten the game without it. While I would try to go through the game on Lunatic, that mode is just friggin' ridiculous. I was barely able to get through the first chapter after half a dozen tries. However, I will admit beating the first level felt far more rewarding and strategic than my time on hard mode.
Has anyone beaten the game on Lunatic? Does it get easier as the game opens up and allows for grinding? Is something like the DLC buffs necessary for success? When can I stop relying on Frederick? How much of your success was just up to luck?
Also, is the DLC sizable and challenging? Would a playthrough with the game's DLC on hard mode provide a sufficient change of pace and challenge?
