That's silly. First, studio glory is absolutely meaningless other than ranking. Nothing is gained from it. Second, think of dueling, glory gains go massively downhill and there is a point where you get absolutely no glory from winning (but still notes and the other benefits). So if considered the same way there is no "race off into infinity."
However, what blocking ANY studio fights does is create a block that prevents studio members from being able to keep working towards successes via studio fights, item rewards, and notes.
It would be rather easy to put in counter-programming that would prevent this type of block, basically eliminate glory gain for fights if too far ahead, and could even prevent trophy snatching if glory is X times higher than a lower studio to prevent a feeling that an OP studio will just demolish lower studios for trophies any time they get one rather than a natural progression back up the chain.
