If you know how all the fights will unfold, all the mechanics of every fight and everything about the game in general, *any* tactics game will be 'easy' because you put 200 hrs into the game and have perfect information. Its not a rral time game where reflexes matter; its a game of tactics and strategy where knowledge determines success, and once you attain knowledgr, of course the game wont be difficult any more. The only way to make the game more 'difficult' would be to add cheapos or rng which are inherently unfun. This is a single player game with fixed encounters and storylines.
In a truly strategic, tactical game, there cannot be a universal master key to victory. Tactics is a living process involving the work of the mind, and not the search for exploits in poorly thought-out game mechanics.
