Personally I think it would be more beneficial for EACH job to have their own "Other" category. Let me explain, Say you are using one of your DD jobs, we would merit Crit Hit Rate+ and maybe something else Enemy Crit Hit Rate- as examples.

Now I want to switch over to a mage job like WHM. I dont need Crit Hit Rate+ but I sure could use that Spell Int Down- and Enmity Decrease.

If each job had this "Other" section as a Tier 3 I think it would be much more beneficial for each job people want to play. Granted I know people have a "main" and "secondary" job they mostly would use this section more, but I feel this will help customize each job a little more.
