RDM is one of my least favorite designs... and I think the only reason why they did RDM's 109AF1 this way is because of the stats the base had.
At least it's not THF... >_>
(probably the only reason it lacks TH is because the base did too)

Though there's a bit of hope for your 119 version...
(and I think they only added refresh to the body to make this an "upgrade"/sidegrade to the empy+2 body... At least that's what I've gotten from the Mage 109AF1s... They all got 2mp refresh on the "refresh" slot for that job... usually body... though I think BLM got a dmg version of whm's empy+1 pants' MP effect instead.... Let's hope for something crazy like a 4mp refresh on them in the 119 versions!)

As to Stymie....
I don't think they're gonna change it....
The most you can hope for... is some effect from a 119AF2 piece somewhere... The AF2+2A pieces would augment 2hrs (usually by extending duration)... so it stands to reason that the 119AF2 might just add charges to Stymie...
But even then it'll still be crap...
But I see something bad on the horizon about Stymie...
Not that it's dumb and will never be used...
But what if new NMs require it's +9999999Macc boost? (I don't think anyone knows the numbers... but the way the Devs have talked about it... makes it seem like it's Macc is greater than ES... almost like it's got +BrewMacc...)
And I don't think we need more PD and FS situations.
