I'm thinking they will give us Dia / Bio IV - which will be exactly the same as 5/5 III, but with slightly higher DOT.
That will clear up those merits for us.

Then they will add a whole bunch of new NMs that are actually susceptible to Paralyze / Slow / Gravity (gravity won't matter because they will be bosses in events that require a full group).

People will laugh at us.

Then 2 years from now when they update the merit categories, they will change all the spell merit categories to: "Increases <enter spell name here> potency." Which will give para / slow %1 more potency per merit (most mobs will still resist it), and add 2 damage per tick to Bio/Dia.

Then red mage will be perfect (if you look at it in a carnival mirror).
