Just thought I'd chime in that this is not entirely accurate. BST, PUP, and DRG actually do have varying degrees of innate healing utility and survivability tools. They might not see much use in typical group dynamics, although they might if you feel your healing is not going to be sufficient for what you're about to do.And I see nothing that says BST, PUP or DRG should be up front meleeing since they have no stoneskin or self cures (well, they might have). As a melee SMN you are naturally expected to play under the same rules as a DRG, BST or PUP. You can't say some melee jobs need to heal themselves and others can be healed by white mages.
BST's Lucky Lulush has an Area Wild Carrot that heals everybody in range for approximately Cure IV amounts. They also have Snarl so, if they do become the target, they can quickly shrug it off to their pet that they themselves can heal (in Abyssea, my Rewards with Zeta heal approximately 1650 HP).
PUP has healing automaton frames that, while it leaves a lot to be desired compared to a living, breathing WHM, is still adequate supplemental healing on occasions. Not to mention PUP's reputation has a hate free nuker itself. That puppet is capable of some sick amounts of damage.
DRG needs to sub one of the mage jobs in the game, but once they do, their wyvern is capable of some of the most MP efficient heals in the game. If they are also feeling pressure from taking damage because they've grabbed hate, they have their jumps to shed it.
So, in a way, yes, they do each have self cures to varying degrees. They even have hate manipulation tools of their own to aid in their own survivability. To say they don't have survivability tools to justify their bid to be in the frontline is completely inaccurate.
SMN? You die if a mob so much as sneezes at you.
SMN can solo things in Abyssea. People might not like that, but just take a walk down Port Jeuno and look at all the people that don't have the gear they want for their jobs. In Abyssea, your ability to get procs counts for a lot. But groups are not always available and, at such times, you would do well to have a job to fall back on if you need to solo. And, at the point of the game that it is now, being able to get loot one way or the other counts for a lot. All I have to say is, if you don't exploit that SMN can solo stuff, Danny DRK and Roger RNG still aren't going to feel sorry for you.SMN is not broken. Definitely not outside of Abyssea. Inside, it's simply not popular, thats all.
BST pets have global recast timers. All of our pet's abilities are on the foul and wretched "charge" system so, even if our pet's have 100 TP, we still have to wait to have the appropriate number of "charges" to perform some of our abilities. Wild Carrot? Sheep Song? Acid Mist? Charged Whisker? Rage? All come from the same charge pool whether they're damage dealing, support, healing, or enfeebling. Calling pets? All on the same job ability timer. Healing HP or curing status effects? All on the Reward timer.I've always wondered why SE gave only SMN a global spell timer.
I'm not saying SMN has it good, but in a way, that's actually the price you pay for being a pet job.
