Splitting SMN in Two

[Exodus-E]

Oh boy, another set of terrible ideas for "fixing" Summoner (while ignoring established lore).
Let's see here...

Less mobile but has new summons to help get around (Atomos portal?).

The Summoner job was conceptualized as an "anti-Primal" discipline by the Allagans, thus doesn't actually summon Primals but rather uses their essences/powers against them (in the form of constructs and powered up "states").
With that in mind, it wouldn't be able to use the power of voidsent (such as Atomos) because they are not Primals.

Permanent egis are lame, demis are better. Therefore all summons shall be demis to some degree, but will still call the small ones egis because it's easier.

Subjective.
Especially since we still haven't seen what the Egis of other Primals would look like.

Moar primals.

Once again, Summoner doesn't summon actual Primals.
Unless you meant more summon variety (which we were promised with the overdue Egi glamour system), in which case, I agree.

That's a good enough base. It definitely takes a bit from MoP's Shadow Priest because that was super fun. None of the casters in FFXIV have an unpredictable Dancer-like rotation so this job could fill that void. Dots can get pretty dull to maintain on their own so a bit of chaos would suit them well, and it would be fun to manage dots in addition to figuring out which spells to cast at any given time.

And there's a good reason for that: because it's not what their (sub) role is about.
Physical Ranged DPS, on the other hand, are meant to be (far) more mobile and bring more overall utility to the entire party, in exchange for lower damage (be it by raw numbers or by having a "random rotation").
Turning SMN into one with a "random rotation" would make it much weaker compared to what we have now (especially compared to other casters), so it's a hard disagree from me.
