End game FE is usually very easy since your units are mostly or entirely complete. Only exceptions are games like Conquest at the highest difficulty, Thracia if you're a first time player doing a blind run or Lunatic + Awakening which is always brutally punishing. Just pay attention to enemy inventories, be wary of the fog of war chapter with Griss, your low Res units will be chunked to single digits or outright killed if they're very squishy. Make use of your Miccy user and your best staves, Bonded Shield death ball and be aggressive, especially in the 2nd to last chapter. You CANNOT slow down or infinite reinforcements will overwhelm you there.
