How about flags can not be robbed on normal tournament?

[Kennoway]

But they can be robbed on royal tournament only.

Royal tournament competition is always intensive because the best prize is there, and that demands a lot of power(manpower basically) to claim. Why not let us relax on normal tournament, pure luck to claim ordinary prizes. And for some players who do not have the source of big amount of BGs coming from salt lakes, grail, they would like to spend real cash for it and try their luck i suppose.
