You upped your cardio though.
To be fair you are mixing up weights and cardio.

You said you did weights and you were still gassed in sparring. Weights doesnt improve your cardio ability. You need to increase your cardio to improve your cardio ability.

In my opinion 2 miles is very short. I run 6 miles minimum every day other than sundays when i do nothing at all, all day lol.

You can do well without weights, i think you can do better with them. I dont like this idea that weights are suddenly bad somehow. In martial arts they have this stigma attached to them, they are only lumps of metal though.
You should mix it up, bodyweight and weights.

so to conclude i think you werent being realistic in your expectations. I dont see how weights can improve your cardio yet you seemed to expect it to, then you did more cardio and you got better at sparring and you concluded it was because of the weights. I think its bad science mate and you should have another think about.

Best of luck to you either way.
