Rule change: Extinction Titans cannot be used in PvP.

They're too powerful, they can be transferred between servers, and there is little to no counters for them. Using a titan in PvP would essentially wipe a base on any server with very little effort. Taming for PvE purposes such as achievements, orbital supply drops, etc is fine. If an Extinction Titan (not a titanosaur) is used in PvP then there will be no warning, it will be an automatic ban.
