Oh don't worry...had the flu a few months ago, was drugged up beyond belief, and made a lot less sense for a few days that you just did.
To make it simple, there are no weapon considerations in the game at all really. The game's scope isn't really tuned closely to the fighting mechanics itself, but the "management" aspect of the fighters. I wanted to keep the game tightly focused, as games that try to be more than one genre or type of game frequently succeed at none.
Fights are designed to be "even ground", to match up their stats against one another. Akin to two boxers entering a ring, each with the same make of gloves on.
Feel better soon!
