This idea just popped in my head about a month or two ago, and this kinda pertains mainly to cats that don't have many people to play against or train with locally... There should be an option for an online training mode!!! Let's face it, many training modes give the option for player 2 to jump in to test some things out, but there are times where "player 2" isn't available, and not all fighting games have the "record function"... And even if there was a record function, you technically would be practicing on a situation you're controlling not because of a trap or setup per sé, but because you told the computer to do this... Record functions do have their purpose and I'm not bashing that at all (I love that ability)... I'm just saying that if you wanted to try out a setup, trap, mixup, whatever, it would be kinda cool to just hop on training mode, and invite that homeboy/homegirl of yours to jump in, and just start testing crap out... You might even get different (maybe better) results...
Now I am aware that local training mode would be better than an online one due to lag and the "lagicities"(tm) of it all... I'm just saying there should be a training mode, with the option to invite someone, or even a few people to spectate to see if they know something that works and they want to see it tried out... I know in other fighting games, I might be training, and a buddy of mine comes through, and they want to try something out, so they go in and I set the cpu to controller, and we might battle for hours, which ultimately helped our defensive/offensive skills, but we might come across or come up with something that we did know 5/10/20/50 mins ago... This same ability should be accessable to people across the state/country from each other and might produce the same result hopefully... That might be too much, but it could definitely help out the scene for the better, especially since KOFXII had that lobby system for 6 players... It would be kinda dope to see training mode evolve into something bigger and better, and in turn upgrade the level of play for people nationwide...
If this ran on for some reason, my bad... I just remembered this and didn't want to forget, so I kinda just started typing...
