ALL ranged DPS apply pressure to healers, it's not unique to SMN. How come BRD, BLM, and MCH get this same "pressure applying" pro that SMN apparently has, but better, AND have better burst and CC on top of it? SMN burst is nullified with a cooldown (not that I'd recommend doing it in every case but it's something unique you can do to counter SMN that you can't counter the others with), they have garbage CC like a SIX SECOND BIND with a long cast time that can be LoS'D, and blizzard II which is actually pretty good. Other than that though they're sitting ducks. BLM are damage and CC monsters with infinitely better defensive cooldowns, BRD has hugely frontloaded burst that HAS to be answered with stunlocking or debuffing, MCH sick burst that actually goes on for much longer than BRD so even if you don't kill someone within 3 or 4 GCDs you're still going until they're fucked, along with some pretty good CC too, both those jobs also have Manasong/Report which is essential for drawn out fights.

But nah man, SMN has bane, that means they're in a good spot. You can bane 3 gimped DoTs, it's great! Face it, the other ranged DPS are better supports and better damage dealers. SMN may not be completely dumpster tier but in comparison to the others it may as well be. The greatest tool they have is Miasma II (which is usually very underutilized by people) and bane.
