They should focus on addressing issues with the jobs already existing. Then focus on creating more jobs options from the existing classes. Like Marauder could go into a Berserker dps job, Archer could become Ranger, more DPS than bard with no support skills. Rogue could become Blue Mage or Dancer, Pugilist could give in an evasion based tank job like Brawler or another DPS like puppermaster. Red mage could be from gladiator. There's a lot of jobs they could create from the already existing classes and they would be easier and faster to create.
As for SAM, i would rather see it as a DPS. We need another melee 2h DPS.

They already said that they'll never do that again. They regret the decision they took with SMN and SCH both being tied to Arcanist.

And for the "They should fix the already existing jobs before creating new ones" seriously guys. We're gonna have new job(s) for every expansion. It's a completely normal thing. Job balance comes in patches, new jobs are coming with expansions. That's how it works and one will never prevent the other from happening.

Evasion based tanks aren't plausible in FFXIV's tanking meta of fluff damage > tank buster > repeat until boss dies.
A tank who can't guarantee he won't die to the tankbuster will be the last pick at all times.
