Lone Wolf and Know it all would be my go-to picks for character creation.
Glass cannon and far out man are both excellent too. Beyond that it doesn't really matter, you'll have so many action points and with Lone Wolf have such excellent spell access that nothing is going to kill you. Ever.
Except knockdown, which ruins Lone Wolf characters. Or rangers with charm arrow.
But the advice by peter is sound - with mages, you need ability points for spells, intelligence to make them strong and action points to cast them. Not much you can do with the first two talent wise, but glass cannon solves the latest issue. It's drawback is you need to invest in constitution (so you can hold all of those action points) and your HP is terrible. Manatarms talents can help with that - at 5, Picture of health DOUBLES your terrible HP pool. Weather the storm together with decent armor and a ruby makes you immune to elemental damage, so really, you get a lot of survivability from those 15 points (and a few useful support spells)
Other good pick could be Zombie - WTS does not cover poison resistance and poison is very common. It creates issues thou, you have to be really carefull when using it.
