Are TCG's the only class of games that have lists of Banned or Restricted pieces?
Miniatures games often have units or models banned if they are over powered or "break" the game. Generally it's less frequent than w/ some CCGs, but it does happen. That said bannings are often specific to a specific tournament rules set (LVO vs ITC for 40k) rather than issued by the creators of the game, especially when the game creators don't actively support tournaments. On the other hand most miniatures companies that do support tournaments tend towards errata rather than outright bans (See X-Wing Miniatures from FFG).
