Since BRD is the only somewhat supportive job currently, I want talk about the "supportiveness" of BRD's kit. When people talk about supporter in game I usually think of the role that can keep buffs up for the entire party consistently. My ideal supporter is a job that pre-buff before boss fight, and re-buff when the effect falls off. The way XIV distribute support skills and their effectiveness barely make the current BRD feel like a support.
I thought BRD songs would be the main source of the buffs, but not really in here.
The Wanderer's Minuet for example: Increases critical hit rate of all party members within a radius of 20 yalms by 2% and it counts as additional effect. The 2% crit rate support portion of this skill is so insignificant it is almost nonexistent no matter how I see. Songs are instead a source of BRD's damage kit. The other 2 songs brings the exact 2% buff to the party that made no difference. They only really affect what skills BRD can use.
Except for Foe Requiem: Increases damage taken by nearby enemies by 3%. MP is drained while singing. Again, I have to ask which dev thought 3% would make much difference? My TP bar allows me to spring for 45s while this thing completely drains my mp in about 10s. Even Contagion from Garuda-egi (SMN) is more potent with it's 10% magic damage taken vulnerability.
Well there are still a few potent ones that are worth calling them buffs, but their extremely long CD plus short duration makes me wonder their necessity outside opening of the battle.
Battle Voice: Increases direct hit rate of all party members by 15%. Finally 15% looks and sounds more fitting as a support skill. The unsatisfying part of it is 180s CD for 20s duration. Boss fights such as ex primal are often set to be done within 11 to 12 mins otherwise rage mechanic kicks in and it's a wipe. So in general, I can only use it at max 4 times and 3 times if clear fast. It suddenly gives a lackluster and very limited feel to it.
Troubadour: even though it's effect varies upon the song currently being used. Due to it's long 180s CD, it has to be used depends on situation. Magic/physical defense/HP boost don't really help all that much when our healers can cast their shield all the time when mitigation is needed.
Then there are the weird single target ones.
The Warden's Paean: casts a barrier that prevent debuff from applying or a 45s CD esuna. It sounds good on paper, but in reality I only use it on myself. I just don't bother with it because healers got esuna. If it is a party wide aoe buff that can help prevent dots affecting my entire party, that would be awesome and useful....Like Selene's Fey Caress (SCH) party wide esuna.
Nature's Minne: Increases HP recovery via healing magic for a party member or self by 20%. Just like The Warden's Paean. I only use on myself and sometimes on tank. If it is a party wide aoe buff....oh wait Eos's Fey Illumination (SCH) got it.
Finally, role actions. This is where the range physical DPS role call themselves "support DPS" while I don't understand the reason behind it.
Refresh: for mp in case our healers/RDM/SMN went oom from rezz too much. In 5.0 everyone will be using mp, so it would makes less sense that it must be range physical DPS to have it and not melee DPS.
Tactician: probably gone since TP is removed in 5.0.
Palisade: This just feels like they throw a tank CD for me to give it back to the tank for the sake of forcing me to feel supportive. Both the description and 150s cd give a bit of déjà vu as I have lvl 70 PLD/DRK.
In fact some jobs, regardless of roles, have at least 1 party wide support skill. Take DRG for example.
Battle Litany: Increases critical hit rate of self and nearby party members by 15%. The buff that makes DRG a popular choice in end game party composition. Battle voice is just the direct hit version of battle litany you know.
So far I don't see any clear line that divides range physical DPS from the rest of melee/caster DPS base on the perspective of a support role. I hope the addition of DNC can actually bring more than what we currently have. Of course, and rework what BRD have. Or should we forget this whole range physical DPS being support DPS?
