I am just a random nobody. I probably don't have the "best" setup out there but it is effective for me and by raiding druids for the past 6 years I am most likely biased towards them but I do like running 2 druids in my 12 man. I run a Zerk/Guard, Bl, Coer, Dirge, Warden, Mystic/Defiler and Sk, Wiz, Illy, Troub, Inq, Fury. Tortoise Shell, Bladedance, Group DP/ Equilibrium, Tortoise Shell, Porcupine/Raidcure is an awesome start to any raid mob burn!

But really it is just personal opinion and comfort level for me.
My opinion is if you decide to put the warden into your group trade it out for the inq instead of the mystic. Druids are just as capable at curing and healing as inq's and you will want the wards. Sure they can't cure while flying through the air (although wardens can to a certain extent with shatter infections and a good timer) but who needs to cure much with TS's reuse at one minute?. Imo the HoT's, Stoneskins, DP's, Sandstorm, AE block, DPS of the warden out-weigh all the inq goodies. I am sure most will disagree though.
