Well I don't like eos/selene getting attack skills for the same reason I don't like smn getting buff/healing pets. The summoner class is flimsy as it is and relies you to fall back on lore constantly for explaining it's sub-par summons and lack of real summoning skills.
I do believe that because pet skills are unlocked based on your level that when a level cap increase happens our pets will also get more skills. They still have plenty of primal skills they could use.
Titan could get a mini WoL or sulpulture type dot on an enemy that increases eminety towards him. Garuda could get a razor/satin plume attack or something like slipstream. Ifrit could get a plume/eruption attack or something.
Eos i would like to see get a skill that is higher priority then healing for removing a negative status or a skill that grants a party wide protect"type" buff that lasts for 5 minutes or something and raises def and mdef i've never seen proshell be the determining factor for choosing a whm over a sch so there isn't any reason sch's should have a gimped protect when it is just as useful. Call it faire ado or something. With selene i'd like her to have an aoe buff that gives a small boost to atk/def/eva/matk/acc
