I think the fact that the cap is equal to the number of abilities for RDM, BLM and SMN (maybe others too?) is not a coincidence. Too bad RDM is the only one of those jobs whose merit spells are so weak at level 1; level 1 AM2s and merit BPs seem to be quite strong and useful (unless I've just never met anyone who has them at any level other than 3), but level 1 enfeeble IIs have a much *higher* resist rate than the original spell (in addition to higher MP cost and recast), in exchange for only slightly more potency, making them nearly worthless in endgame settings.

I wouldn't be opposed to some cap increase, but I also wouldn't be surprised if there wasn't one and RDM remain unable to get all their merit spells at effective levels.
