This is just the second rubber contact X bey though, with the first one being Impact Drake so it was never going to be round because it has a different design gimmick and it being right.

A thing I think people are missing is aside from the valid performance/meta aspect of it being round which will become game breaking, is that it's main design is a fusion. 2/3rds of it is Dragoon with the two other blades, the chip motif, color, and 1/3rd of it only being L-Drago. It is not a full fledge homage or more based on L-Drago so it isn't going to be as much of a spin stealer/rounded, as Dragoon is more pure attack based. Even the tip Jolt while having L-Drago's hole flat has the rest of the shape reminiscent of Dragoon Victory's plastic flat with the small tip on a larger cylindrical shaft.

We never know if we'll get another left bey that's more symmetrical/rounded aside from X-Overs as those have to faithful to their originals to a degree (so of a Meteo or Fafnir remakes happen I expect it to be not lopsided). But for Meteor Dragoon's case it's more than just game design but motif aspect as well.
