Honestly since 1.6 a Templar is free APs in Cyrodil. They have no survivability since Blazing Shield became useless after being nerfed in three different and significant ways. They don't have any offense apart from weapon skills, so all they can do is run or die. The only thing you can do with a Templar is shoot at people with a bow in large zergs, or heal while you hope you don't get focused, as there is no way to survive.
