No offence intended, but using boss weaknesses is easy mode and the regular intended difficulty of the Megaman games is not using them at all. You can even go one step further and beat all the games without any additional upgrades or tools sans the mandatory ones in X1, which became regular base abilities in the sequel games anyways.

The reason why they're a thing over the usual difficulty slider in the settings is because fucking up a tough enemy with their weakness is far more satisfying, than merely beating it with your same weapons but it has lowered damage/speed/health than normal. It also feels better, because you're subconsciously thinking "I have outwitted my foe by exploiting their weakness" rather than "I'm a pussy that needed to reduce the difficulty to best this challenge". It's a far better way to handle game difficulty.
