Ok, i'll keep this simple. Yes it needs reworked.
SE is trying to make SMN pet job easy to play, and they've succeeded - but to accomplish this they give SMN no utility.
Unless Garuda is on Obey, she uses contagion too early. So why not just rework SMN as a support role since it's already fiddly to get her to work right ?
Now, let's be honest here - Titan and Ifrit egi have little to no use in a dungeon past level 40. SMN has limited AoE damage, which has to be set up.
No utility aside from an in-battle raise. No unique Limit Break, buffs or debuffs.
No unique pet buffs, party buffs, or abilities. So what's left ?
You get Garuda, Contagion, and an in-battle raise.
Looking ahead to the potential of Leviathan, Garuda, and Shiva egi's...
the SMN class needs to be rebuilt from the ground up as Support, period.
That's my 2 cents.
