Something that I don't see a lot in these discussions about the Healer role is their DoT actions and how dull they are. This has likely been brought up in the past, especially in SCH threads, but Healer DoTs need a rework on how they play out for each Job.
Each Healer DoT is an instant cast ability that has a duration of 30secs.
That's it.
No interactivity with the rest of the kit. You just press it once and forget about it for thirty seconds. To be blunt, this is bad. Really REALLY bad. Especially, when you compare Healers to Jobs like BRD and BLM, who have more interactivity with their DoTs (still surprised BRD is keeping it's DoTs in DT).
So how do we fix this?
I think the best way to alleviate the problem is to have the DoT durations decrease to the twelve to twenty-four second range. Maybe decrease the durations to 15 or 20secs if SE wants to keep it within the two minute meta. This change is minor, but it'll be a benefit for us because we'd be pressing the button more and it'd help alleviate the 1 button spam all healers are guilty of. It's not much, but anything helps.
However, I think we can push this further and have each Healer Job have their own unique interactions with their DoTs.
WHM
Give WHM it's own version of BLM's Thunder proc and BRD's DoT procs to Straight Arrow. Since WHM is getting a new DPS action, let Aero / Dia have a small chance to proc into the new DPS action, with WHM getting a weaker version of the new DPS action at a early level.
SCH
SCH needs Bane back. PvP SCH already has Bane in the form of Deployment Tactics, so having that version of DT carried over to PvE SCH would be great. For the sake of interactivity, give the Job a DPS action whose potency increases depending on how many DoTs are on the enemy NPC. Looking at you Ruin II.
AST
I honestly have no idea. Can any AST player think of anything for Combust?
SGE
It's getting an AoE DoT in DT. Have that and it's single target DoT stack with one another.
Feel free to post any ideas that you can think of.
