I probably listed a bunch of Magery type templates
You listed three Magery templates. Each of which varied by one skill.
because that is what I am comfortable playing
Right, so if you're into playing mages, you effectively have 1 option. The differences you list are like getting one option (say AC) on your car instead of another (say, a stereo). Sure those are considerable differences, but they aren't the sort of differences you might see with a variety of casting types, for example.
when it comes to field PvP and not just 1v1 stun is a very important skill I do not see why anyone in their right mind would give up a 3s stun.
You're making my point: the number of viable templates is severely limited.
