So Soran is a grade 3 combatant? Because he's got 10 levels in combat professions. Surely he wouldn't be considered grade two if he had 9 levels in rogue and 9 levels in wizard.
The problem with that logic is that there are supposedly important benchmark abilities you get each time you go up a Grade, so even though he has more stats, abilities and skills than a normal Grade 2 he lacks the biggest differential of a Grade 3.
