Thats one thing that Yoshida "fucked up" at this point.
Still the Dark Knight has his abillities which you expect him to have (more or less..) .. and still Dark Knight isnt able to become a healing paladin either. But thats what you are asking for. Well why dont we let all DDs have heal then? RDM has heal for reasons, he ever had access to all professions but not being perfect in any of these, still he has the dd role but i doubt that he comes close to the damage of a BLM.. and thats why to sub-heal may be a unique point why you still would get a rdm in... the reason to get a SMN into a party shouldnt be because he is able to heal in my opinion.
Ask for a decent pet heal instead of asking to heal party members since it even doesnt fit your role or job class in this game here either.
WHY DONT YOU GET THIS?
ASK SE to get PET HEAL back... instead of having physick and that should be totally fine!
As i already said before.As already pointed out to you, virtually every summoner (like, ever) had heals in the FF canon.
FFVII - FFX , FFXIII, FFXV. All had no job system!! EVERY CHARACTER was supposed to to everything! It was about characters and not jobs !!
The FF Online titles make use of the classic job systems of classic FF titles like FFIII and the tactics titles.
THE SUBJOB!!! Summoner in FFXI couldnt heal at all except carbuncle with "healing ruby"In FFXI (the only other MMO), white mage was pretty much a standard support job
That already i have written before.Why is it fine for Red Mage (a DPS) to have a heal but not Summoner?
Red mage as a FF job class always had access to every profession of magic (Black magic , white magic) and so also the access to cure. Though he cant do any of these in perfection. Same for the RDM in FFXIV, he wont do as much burst damage as a BLM but has the abillity to sub-heal (weakly) in emergency situations.
As for the SMN traditional job class it never had access to real except via its summons.
And no in FFXI as i said the summoner couldnt heal either.
And now granting all DD's heal.. would destroy the unique thing about RDM in FFXIV, too.
