5-6 players, to be more specific 3 DDs, and 2-3 pullers (BRDs, CORs, and/or THFs). It's the fact my party doesn't gear swap into stupid setups. I'm guessing you have or rather prefer DDs who sit in PDT sets where as I'd much rather they full time the optimal TP and WS sets when we're just talking about fracture plasm farming.
Actually a WHM is just as much if not more MP efficient when they are focusing on cures at least when done properly.
Actually Genbu's shield is simply left alone because there are issues with gear swaping via macros that gets weird with sub slot. The only reason I have Genbu is for it's augmented Cure potency and -cure casting time. The PDT is irrelevant to me as I have a PDT set as well though that doesn't see the light of day much because well I'm rarely stupid about my curing reducing the chance of me pulling hate in the beginning of fights.
In a good group all 3 DDs are sharing the tanking duty not just 1-2 DDs. Regen V is awesome except when the monster pulls off a TP move that ends up doing 1k damage. While that DD may live long enough to have a few regen ticks heal him up I sure won't be finding out because I'll be tossing a cure to ensure cure + regen keeps him alive.
Not having to depend on Rapture has always been my goal, that leaves my statagems for buffs and aoe debuff removal, or a pinch aoe cure.
They're busy pulling because that allows the DDs to focus on killing as fast as possible and I am more than able to focus on curing without the need of supports tossing in cures. Helpful but I definitely don't depend on it.
I use convert assuming I even need it, Sublimation + refresh gear I swap back into after casts are often more than enough. If I get low on MP then I still have convert to fall back on which doesn't lock my main/sub slots. It doesn't require another inventory space taken up by a Dusty Wing.
Never said I needed the weapon slot for my enhancing set, though for most people Kirin's Pole augmented is easier to acquire than other options.
I don't need to depend on Tabua Rasa for Embrava or Stratagems. I'd wager because my "overgearing" allows me the comfort of not ever having to look at them as pinch solutions. Though I do agree they still count as that well assuming you have the MP to cover the costs.
Maybe not having 50% is acceptable to you though to be frank I bet if you aimed for 50% you'd find you need the MP from Myrkr and Vile Elixir/+1 would go down.



besides that I've no interest in those objects... and i own an irridal staff of which i do use for my drg
