Summoner gets no new pets in expansion

[Dement]

Bottom line: FFXIV's pet jobs won't be get any new pets in Heavensward. Everyone agrees the pets need work in one form or another and this is a missed opportunity to work on those issues. In fact they said the max they are doing is adding a glamour system but leaving pet abilities effects the same.

I think you may have misunderstood. While it's not mentioned in the notes, in the spoken live letter they talked about buffing the current pets, altering their abilities and adding new ones. Specifically at around 2:13:00 the translator mentions "Rather than adding more pets where each of the entities won't have any change of effects, we decided that it's better to bolster the current existing pets and kind of add actions and expand on that." So I don't think we can say that it's a missed opportunity at this point. Everyone agreed that SMN as a whole needed work and SMN as a whole has been reworked. The rework just didn't involve putting in more redundant pets.

What you're talking about with the same effect is directly tied to the glamour system. For example you can Summon I a caster type pet which you've glamoured to look like Shiva, you use Wind Blade but since it's a Shiva pet, it'll probably be called something different to make sense for Shiva and will have the appearance of ice instead of wind. So leaving the effects the same applies only to the glamour system but that's not to say that the pet abilities are going to be the exact same as ARR.
