This rule is indeed very novel and puts a strong emphasis on teamwork. Among the top talents of the Ten Great Sacred Grounds, the gap isn't too significant.
Even if someone is strong enough to take on three opponents alone, in this kind of competition, they may not be able to withstand the hunting by other teams, wave after wave.
After all, this rule allows for forceful snatching. As long as you don't kill, any form of plundering is acceptable according to the rules.
This means that this competition will be filled with all kinds of intrigue and schemes, all kinds of crafty and bold maneuvering, and all kinds of calculating traps.
In this case, the team is not just a support in terms of strength, but also a psychological reliance.
Being a lone wolf, it's very difficult to stand out.
