All of the following is my opinion and, as such, isn't worth a single pryeal

but here are my thoughts from reading and playing around with a few mage characters.
Part of your decision depends on whether you will use buff bots, or a buff buddy, to help give you that "little extra."
Borg's template was, I think
Strength: 40
Endurance: 60
Coord: 10
Quickness: 20
Focus: 100
Self: 100
Your mage's starting template isn't critical like it used to be, since you can redistribute attributes now.
Focus: 100
Self: 100
Coordination: Coord is of absolutely no use to a little mage. Later maybe, if you choose to take melee defense but you can redistribute points into coord then if you really feel the need.
Strength: Strength is important, sort of. It isn't nearly as important as it used to be when you had to carry a mage shop's worth of components around with you. Tapers are heavy, but manageable.
Quickness: Quickness will help you get places a little faster, and run away from monsters and hopefully not die. You want a painful experience? Try an overburdened mage with a quickness of 10.

Folks might argue on this one some, depending on their mindset. Is it better to run away and stay alive, or is a lot of health better so you can duke it out with a critter? You probably won't have both. I think I remember reading somewhere that the ingame animations need a quick of something like 70 in order for your character to be able to move as fast as the animation sequences, but I could be completely off on that.
Endurance: Endurance = Health = a bigger stamina pool to do transfers from. For PK, I would think you will want all of the health you can get. Endurance is going to come at the cost of quickness or strength though.
I think I started Borg out with 60 Endurance I think and 40 Strength, not knowing exactly how strong he needed to be. After some painful and slow fighting, I raised his quickness up to the point where he was okay. I've been transferring strength over into endurance lately so I can take more of a beating. His 10 extra quickness have long since been moved to strength. If I were to re-roll him, I would start him with probably 10 strength and depend more on a buffbot to give him some muscles.
