I think some of the tier 2 Merits should be changed for ALL jobs, for melee those merit which are Job Traits should be removed and given to the job by default at a certain level. example Iron will, Ninja Tool Expertise, Winning Streak, Overwhelm etc
And for mages Spells and BloodPacts that are learnable as merits should be removed and made available via scrolls (and blood pacts learned by avatars at level 75) example: Protectra 5, Blind 2 Flare 2 etc

And Replace those Merits with all new ones, ie merited Job Abilities
