RDM is a luxury support for large groups. It also fits into a 6 man like ambu if you are capable of doing damage and scing well. However you have to be geared to the teeth and to be perfectly frank, i know very few people that have geared their rdm to a competent level. I know it's going to sound snobby but AG your Murgleis or don't expect people to be happy to see you. And if the bar is that high, why not make any other job with a good/better mythic? (The answer is you're obsessed with RDM)

The job is a passion project rather than a required job. In wave 3 dynamis frazzle, distract, and innundation are amazing contributions to an already well stocked alliance that has multiple other supports and buffers. But you need a gross amount of magic accuracy to play the job well and land your spells fast. You need glowy murg, omen shield and ammo, relic +3 head and feet, af+3 body, chironic pants with 35+ macc, raetic bangles +1, stinky ring +1 x2. I have all of the above except the raetic +1 hands, this job is so expensive! Bio3 has also become more attractive to take the edge off wave 2 bosses. Para, slow, and addle will all land on bosses as well but that's all just extras and the more enfeebling magic effect gear that gets put into the game, the better they will help to soften dangerous mobs. Sleepga from /blm or /sch works extremely well on wave 1 and 2 mobs, however no one can sleep wave 3 mobs consistently outside of their pets or the use of Stymie.

RDM isn't going to compete with GEO for overall support, nor will it get close to the total damage contribution of a COR. Those are the popular jobs if you're looking for easy to fit into a group. They are easier to gear and have softer requirements to be effective and contribute to party play. I didn't address how to make RDM great again because it already is if you already have the gear and the ls group to run the job. Otherwise it's nonessential and I'm saying that as a career RDM who barely plays anything but RDM.

Devs don't need to add a bunch of stuff so much as they need to not squander our gearing choices. +20% FC on the new dynamis sword? Who is su5 that would think that is good? We needed more enfeeble magic effect or skill, quick magic II, or immunobreak +1. Hell we could even take critical hit damage or ws damage for when we are low manning. ANYTHING OTHER THAN FC THAT IS GOING TO GO WAY OVER CAP.
