Saying "Well, if that ability works too well and makes everything else pointless, why don't you just not use it?" is patronising, and frankly, a little offensive, as well as being dismissive. It assumes I'm not, and it ignores the fact that doing so will not, in any real way, improve my enjoyment of the game, when I know that the "I win" button is there, at all times, and that I'm just wasting time and being ineffective for no functional reason by not using it. It's not a "ruining your own game experience and then being upset" situation - it's a "Damned if I do and damned if I don't" situation - and that is a fault of the game's design and balance. If I could turn my brain off and be mindlessly entertained by the flashy colours and bright explosions, and the game congratulating me and telling me I win every time I push the same one or two buttons over and over, perhaps I would, and perhaps I'd enjoy the combat in this game if I could: I can't do that... I need the game to be better.
Except it's not directly patronizing to you in the least and there's no reason for you to take it personally.
A large number of mass-appeal games have easy-win mode because that's want the majority of paying customers want, easy entertainment, not a challenge.
If you don't like the game the way it is and can't handle not using easy-mode then you move on or wait and play something else to see if they release an increased difficulty level.
