Maximum stress on the drivetrain, maximum wear, it's almost always the noisiest gear on the bike, and the ratio almost always ends up being a duplicate of another gear, unless you specifically design the gearing so that it isn't, which nobody does, except for half-stepping weirdo gear-freaks. And even they avoid the big/big.

Just say no.
