Ton of useless posts without any explanations. So that's been cleaned up.
To answer your question - You're given a small arena to fight, leaving the arena causes you to lose. Obviously, that lends itself to a meta of using any technique that either a) lifts the opponent out or b) counters lifts by striking at vulnerable joints. In most high level play, both players actually will either go for a shovel, or a direct shovel counter. That's the nature of the mod. There's a skill to lifting, and there's a skill to not being lifted and staying low.
To put it as Diamond told me back when I was trying to learn from him (as I consider him one of if not the best aikido players and general players in TB) - the best way to learn how to stop getting lifted is to not get lifted in the first place. He's right, there's a lot less technique involved in how to land and there's a lot less decisions to make once you're in the air. The decisions that become critical are the ones involved to make sure you don't get lifted in the first place.
I guess you can be like Snake and only play with friends who abide by their own custom rules or stipulations if you can't handle playing optimally, but I'd advise learning from the experience instead of raging.
