Pokémon Showdown! only has the Unown-A which limits people in the forms of Unown that they can use.
This has gameplay significance in Gen Ⅱ. In Gen Ⅱ Unown's form and shininess are dependent on it's DVs and therefore the form and shininess gives information about Unown's DVs. This in turn gives information about Unown's Hidden Power due to Hidden Power also depending on DVs.
I like buffing Unown but I do not think that Pokémon Showdown should buff Pokémon by implementing them incorrectly as it is doing now. Besides that, the people of the Help room deserve Unown-? and the people of the Ruins of Alph room deserve every Unown!
