I fail to see how the game is easy with that statement. The planning and knowledge to run such a planned out series of action is half the challenge on its own.
Quite. It's another story if you find the game easy even when playing casually, trying out various tools on the fly, making mistakes now and then, without relying on any ultra secret super strong combos and without any exploits. But when it's a case of extreme powergaming, there isn't much merit in your claim that the game is too easy. You figured out one single most efficient party combination, along with a very specific procedure on what to do and when, which is to be applied in every single encounter - well, good for you. But to claim that the game is "easy" based on this, is rather silly.
In this case, what you're asking for is not simply "a harder difficulty". You're asking for something that can completely shutdown powergaming. A modder with the same mindset might be willing to try and accomplish this, but there's no way the developers of the game would, or should.
