If Verraise and Vercure are going to stay then they should be changed to mitigate losses
Vercure can function exactly the same except it gives you a 100% guaranteed Verstone Proc.
Verraise should do the same with Fire procs and could possibly double the potency of the next Spell expended by Dualcast. This way, Verraise is at least not a dps loss and neither stops the rotation flow. Vercure would also be even better during downtime as you have the chance to get 2 procs once the boss reappears.
My personal problem with your idea of verward(aside from the uninspired name and manaward isn’t even a spell so it wouldn’t get the “ver” prefix) is that it’s a GCD and 2nd, RDM needs more party wide utility. Ver”Medica(2)” as an OGCD is a wonderful idea here because RDMs Kit is too far in the worst case scenario. Good defensive cooldowns on dps should aim to support the raid prior to someone’s death while not costing the dps damage. Mantra, Addle, Troubador are all perfect examples of this. RDM is currently paying for worst case scenario utility and as a result, it’s entire usefulness is front loaded in the idea that your run might wipe. It’s the worst job in the game until your run needs to be salvaged in which case. It’s broken.
The jobs value swings way too far into uselessness or brokenness and there is no inbetween. RDM as a result pays for the brokenness of its kit and the practicality of it gets completely ignored. This is the fundamental reason why RDM struggles in this game
