Well, you should open your eyes in the forums and look for less positive threads on Templars. Do not get impressed by "fotm PvP-templar videos" (from players like BumBumBoom).

Your best alternative, if you want to go on with your templar in PvP, is to find a guild as fast as possible and join them. If you want more "liberty of choice" and you're more a freedom loving PvP'er (mostly solo), you should reroll another class like NB/Sorc. As this company has very long "class balancing" times, sometimes up to a year, before the situation changes and NB/Sorc simply offer you much more choices, much more direct skills (less channeling skills, less or no animations at all), better sustainability, get-away skills + mobility, which is the key to success in zergy PvP. Or you make it easy and try to find a group, and then you become their healer (in chains, that means you have to use the same skills over and over for years, though some templars like that style)
