Just got an awesome idea for a weapon loadout req

Halo CE 60 Round AR. No attachments or anything. It basically works and does the same damage as an SMG and you unlock it at req level 3. It should also be a legendary or mythic card.

would it not imbalance gameplay?

like I said. It’s basically an SMG at req level 3 with mythic or legendary rarity. If it proves OP they can always bump it to req 4.
