I've actually never felt the need to have summoner player like 10 or 11, only rather be more pet focused as a whole to give meaning to the actually identity of being a "pet class." I feel the job should of had its damage split 50/50 between person and avatar/egi. The Dreadywrm stance was a nice direction change from sliding it away from arcanist sub class. If they don't plan to move more on that direction they could differ from scholar by adding traits to the current spell list for example:
Contagion=Base SMN spell not pet skill
Bio=dot damage increases damage done by summons by 10%
BioII=decreases damage resistance from avatars 10%
Miasma=decreases magic resistance done by avatars 10% for Garuda out, decreases physical resistance by 10% if Ifrit out.
Miasma II=Applys dot restoring hp to summon and summoner with every hit done by egi.
Enkendle: Signature Pet attack can be executed once all 4 dots on target.

I mean these are just example on the top of my head haven't taken balance into factor yet.
