According to the Spelling and Grammar Standards, Tauros-Fire and Tauros-Water are to be referred to as Tauros-B and Tauros-A, respectively. Since this is the proper way of referring to Tauros' formes, I'd argue that they should be renamed on Pokémon Showdown! to "Taruos-Blaze" and "Tauros-Aqua" as to not confuse newer players, who likley will not understand what Tauros-B and Tauros-A stand for in analysis.
