2. Mages aren't even (as a rule) trained for combat.
I'm not sure what criteria he used to reach this conclusion, but to say i disagree is an understatement.
The criteria i would use is - do they have Combat training - in this case, represented by Palladium's "Hand to Hand Combat" skills.
So lets do a brief run-down. This does not reference every book (as i dont have them all) and i left out Dimension Books on purpose for now.
Ley Line Walker/Rifter - Basic
Mystic - None, requires 1 Other skill for Basic )or a secondary skill
Shifter - None, requires 1 Other skill for Basic (or a secondary skill)
Techno Wizard - none, requires 1 Other skill for Basic (or a secondary skill)
-- it is worth pointing out, however, that not one single NPC of these three classes is EVER seen without at least H2H Basic.
Temporal Wizard - None, requires 1 Other skill for Basic (or a secondary skill) - No Temporal Wizard NPC is ever seen with out H2H Basic, however
Temporal Warrior - MA or Assassin (choice)
Herbalist - Basic
The Three Woodland Druids - Martial Arts on 2, Basic on the other

So, that's a total of 54 spellcasting magic using classes.
Out of that 54 classes, all but 9 have combat training by default. (so, 84%)
For at least four of those, there are NO canon sources showing those classes without H2H skills. If we add those back in, we're at 91%.
ALL of the classes that DONT start with H2H skills can also be classes that, in the setting, may legitimately never see combat (healing shamans, grey seer, TW, Necromacner, Shifter) as they are either support classes like a TW or healer, or can use minions to do their work for them (Necromancer, Shifter).
Seems to me like the rule is that mages, particularly any mages who are likely to see combat at any point in the careers, are likely to be combat-trained. The exceptions are the ones that dont have to seek direct confrontation or could expect to live out their lives in a support role or without adventuring (a TW working for Arzno or the Baronies for example, who never gets out of his shop).
TL:DR
Mages who aren't combat trained are the exception, not the rule.
