From /WHM you get Cure I through Cure IV. That's the same amount of healing prowess that any non-WHM Main gets. You also get more than enough Healing skill from the sub, and base MND, to hit the soft cap on all four of those cures. So with a /WHM sub on any job that has native MP, you're basically a mini RDM/SCH/PLD, and if you wear any compatible +MP or +Cure potency or +MND gear, your cures can stack up pretty well. Your cures will never "miss", either.
Melee wise, though, you are very much bound by your main job's prowess. You cannot feasibly, say, go WHM/MNK, equip Trainee Scissors, and expect to hit anything let alone deal relevant damage, since your combat skill is so incredibly significant to your ability to wield and swing the weapon. Even among main jobs, you don't see competent Warriors trying to main Dagger or Polearm instead of axes because the skill deficit just plain hurts too much (that and the severely nerfed weapon selection of course).
Even more relevant example: you never see Dragoons maining Staff. Dragoons are infinitely more capable of wielding a staff well than a Summoner - they get Accuracy Bonus job traits, and their combat skill at 90 is only 10 points below Summoner's. It's just not worth the severe cut to your attack and accuracy compared to a primary weapon.
Puppetmasters are permanently hobbled by their weak h2h skill cap, and it's 6 points higher than SMN's final Staff cap. Even when PUP's skill cap was raised from ~C to B+ it was still considered a bit of a slap in the face, since B+ is still a whopping 13 points behind an A- weapon - that's 13 attack and ~12 accuracy lost.
And that's all before even considering the actual Melee jobs' exclusive gear (SMN maxes out at 23 haste from gear, EVERY dedicated melee can hit 26 comfortably alongside other relevant stats) and job abilities/traits which can't be subbed.
Oh, and if you want to play a real healer, play WHM. Cure V&VI really are THAT important. Just thought I'd throw that out there.
