Frankly, I've never liked the Role Actions system. I always felt it took away from some of the class identity to have the exact same skills shared across Jobs. Rampart is a Paladin skill, Shadowskin was a Dark Knight skill, and Warrior had a different system entirely with Inner Beast... That was much nicer than all three (soon to be four) having Rampart...
Increasingly though, I find myself questioning what is even going on with this system, when there is seemingly no consistency in what actions this applies to... Every Tank has Rampart as a Role Action, for example, but then every tank also has a Sentinel/Shadow Wall/Vengeance/Nebula... Every Healer gets Esuna, but why do they have Raise/Resurrection/Ascend... Why are some skill put in the Role Actions while others aren't?
I'd really just prefer to see skills like Shadowskin and Leeches return, on top of new unique ones for the other Role skills... It adds to class identity, and I honestly always through there was room to differentiate some of the skills... Different cooldowns, slightly different effects, different ways of delivering the effects (this is particularly true for Pet Jobs), different integration with Job mechanics and gauges... I guess class homogenization is the order of the day now, though... Seriously though... In the same expansion that you added Job gauges to try and give Jobs more individual flavour, you took aside a bunch of actions and said "These will be the same for every Job and wont integrate with the new Job mechanics at all"... Why? Such a bizarre choice... And you're sticking to it with Shadowbringers...
At least at the start of Stormblood the concept made sense; You have 10 actions, you can set 5 of them. Obviously the system didn't work, because some were out right required, while others still sit unused, but the concept of picking a spec at least made sense to me, even if the implementation was absolutely terrible... Now though? You wont even need to set them as we do currently, they just sit in a separate category from the rest of your combat actions for... No reason? Esuna sits under Healers Role Actions, but Raise doesn't for... No reason? Just give us unique versions of them and help fix some of the class identity you seem to be trying to wash away lately...
EDIT:
Oh, and on the subject of Raise... That really should be a Role Action... Obviously all the Healers have it already, but so do 2/3 of the Casters... I wouldn't even object to Black Mage getting it, and Blue Mage has enough KO-self mechanics that a Raise spell seems fitting for them too... Obviously Black Mage getting Raise isn't particularly fitting though, but this just highlights again why its better to not have Role Actions, and instead have the same concept for actions across roles, with different implementations. I think a Necromancer type approach to Raise on Black Mage is pretty fitting, and Dark Knight already provides us with the Walking Dead status effect needed to make that work... While I'm here, Summoner shouldn't have just Resurrection, more so now that it's getting Phoenix... Why not give it a Raise that isn't a complete DPS loss? AoE Fire damage around the fallen party member you cast it on, animation incorporates Phoenix. And Blue Mage... That's almost certainly getting Reraise out of Amdapor Keep (Hard) already, so whatever... Red Mages Verraise already functions somewhat differently by virtue of Red Mages Dualcast mechanic IMO, but it being the most basic, and similar to White Mages Raise also makes perfect sense anyway. Scholar? Why not have a variation on Dissipation, sacrifice the Fairy to revive someone. Astrologian is the only one I'm having trouble with, mainly because the Time Mage aspects have been wiped away (although I doubt a Rewind mechanic could even be worked), but I'm also not paid to come up with these ideas so I'm not really putting much thought into any of them to begin with, and yet most of them still seem painfully obvious to me... Like really, how has nobody at SE thought of giving Summoner a Phoenix based Raise instead of lame old Resurrection?
