The thing about upcoming job Lethe is that she really should be a dedicated support job since having a bunch of summons to do your bidding with no attacking skills works really well as a dedicated support - you can focus on supporting your allies better and still deal full damage to the boss at the same time.
Now this concept is going to be a more extreme version of Lynn where you toggle on summons, have even more summons than bird and wolf, but zero attacking skills.
To make the concept playstyle exciting and fun, and something to always be doing, you are focused as a dedicated support that makes combinations of Material skills to form an Alchemy Enchantment (same character can only have 1 enchantment active at a time, a new one replaces the old one) that affects self, party members, and your summons! With the enchantment being a short duration to make you into an active buffer and your summons will not move around and attack monsters unless they have an enchantment currently active on them - summon AI logic will be similar to Lynn's bird and wolf.
This concept will also have a beginning skill that starts out blank, but every time you perform an alchemy combination, it will record what combination of materials were used to form it and what bonus enchantment effect resulted from it.
This concept would be easy to play, extremely difficult to master!
Concept is a Mage Class.
NOTE: There is no vertical or horizontal jumps, you only have a teleport.

Comments
1) Attack speed gains aren't really supports when every class plays at their highest AS if it gives them extra FD, and other classes that benefit from passives more are fine as-is (i.e. Lynn) for the most part. AS bonuses don't really help hurricane classes.
2) I don't really understand how the final damage support would work. Also, for 3-man party bosses (higher-tier grandis bosses), life counts don't really matter as much because the bosses use gauges like willpower, erosion, adversary determination or whatever it is first adv uses, Hunger for the licky boss.
3) Damage reduction doesn't really do much in the higher-tier bosses as well, and people already have Ren link skill for damage reduction, their own class iframes/damage reduction frames (if any), ascent skill iframes, and genesis iframes.
I think maybe a combination of final damage boosting + giving extra lines to party members for their attacks or acting as a class-based cooldown hat (which would reduce the amount of investment needed in hats in reg, for example, for cd-hat classes, which can run into the thousands of USD), replacing heals/dmg reduction with something that reduces the impact on gauge-like systems for bosses (reducing the amount of erosion you get, for example, or preventing you from losing gauge if you get hit because you missed a parry) would benefit.
Also, cooldowns on skills should sync to a 2 minute burst cycle, so having skills with a 90 second cooldown would be hard to sync
Additionally, directional teleports should be diagonal as well. A lot of people probably won't necessarily want to use the mouse feature.
You should keep in mind that with any new class kit, people will find the optimal combination/strategy to maximize dpm, so a lot of the combinations you've listed will likely be DOA unless each combo is ideal for various bosses. Enchantments should be made to be suited to specific bosses and keep growing with new bosses, because one of the reasons we've moved away from supports as a meta in KMS is because bosses have moved to 3-man parties and KMS didn't want people to be relying on supports for clears. We now have wild hunter potions (sayram's), phantom potions (the 6 minute ones), decent holy fountain 5th job node, and so on. Clearly, though, supports are desired in MMOs, and there are other ways to make them useful outside of bossing.
For example, if you clear a boss with an alchemist, the party could get drops added to the boss loot box that give them benefits outside of bossing, such as enhanced spawn rates, better luck at hitting a desired line or a pity system (cubes, flames, starforce etc. to reduce RNG elements without removing RNG altogether, since one issue we do have is that there is no pity on cubing, which can get really expensive in Interactive) 3-day long or week-long enhanced mesos obtained % effects, or in Interactive, crafting material that can be extracted if you have a meister alchemy profession that gives you materials to create solid cubes, such as chaos cubic blades, so you could create 40 to 50 solid cubes a week perhaps, or materials would be used for the cubing pity system, to encourage people to run with the support). This could also help ensure that even if metas change or support inside of bosses gets nerfed like what happened with bishops, BaM etc, they would still be 'supports' for overall gameplay
