It's good to try to improve in the game, I mean, trying to become good, to have chance of winning matches, and being satisfied on having enough skill to have more wins than loss, and not being a "noob" forever or a "online punch bag" ....
Summarizing : having chance to survive, and winning more matches than losing, and having fun knowing you can do moves, fatalities,combos and put a win too, when you played better than your oponent ......
Anyway, Personally I take well and light being defeated and having a loss online, specially when I see that I have been lazy to try to win , and the other guy/girls played much better than me, he/she really took that match serious and put effort to win it .....
It's OK being half/half , 50%-50% : being competitive, but , knowing how react on victory and the same attitude on loss ..... basically , being cool , and having fun , winning or losing ..... and, in fact, losing is unavoidable, and happens to improve your game , to show how you sucks and need to go in Training Mode more .....
I know some confident guys will ignore partially or totally the training mode, and go straight online at first to play only vs online, but, some of them having their assess kicked later, when some others guys that spent time training this game, feel prepared to go online and put competitive battles ......
Regarding MK 2011 Life Cycle Improvement time line,picking a newbie that intend to be a pro, I think works more or less accurate as this summary above :
** Having the game for 1-2 weeks : when the game is released, you spend the first weeks "feeling" it, training, playing some matches online, and accepting well defeats when they come ....
** Having the game for 1 month : With one month of practice, you start to become more good, more quick, more smart, and more daring, trying more of your personal touch in the game, and copying less other's people style and gameplay ....
** Having the game for 3 months : With 3 months practicing, you do pratically everything naturally , the moves commands turn into a second nature, you start to take more serious a match and try to win, and , if you lose, at least you fought hard ....
** Having the game for 6 months: With 6 months, you know pratically everything about the game : basic and custom combos for every character, all offensive tactics, all defensive strategies, and probably, you have a win/loss rate about 5:1 or even 7:1 .... at this point the game has none secret anymore for you, and you play to keep training, avoid rust, and become pretty competitive ..... you still accept being defeated, but, only if you see your oponent really, really put a hell of battle and he was better than you in that match ..... against any other person below your skill level, you have no mercy , and destroy them online. Against MK 2011 newcomers, you can only lose if you want .... hehe
** Having the game for 1 year : With 1 year having the game and pratice, you could easily do well in any paid tournament, since, at this point, you are so skilled, that playing with people much more worse than you, becomes "boring" : you want to test yourself in high level, and so, online you seek for right ranked players, you send messages in forum wanting to play with people who are so skillful as you, and you want to break all game's limit, doing super hard and crazy combos, long combos sequences , and trying to put some hard flawless victory .... from this point to foward , if you are still motivated, you dominates totally or almost all aspects of this game ..... you can keep a 10:1 w/l rate almost all the time .......
