I've to agree to some extend. I raid 10Man and I'm kinda always comming out on top on healing done. I guess druids have to be carefull dropping efflorecence this patch, since its great if i hits more then 1 player. In my guild we don't have a cooldown problem with tanks (paladin + warrior) having raid cooldowns we're usally fine. I time my ToL just before the raid start taking alot of dmg so I got people pre hotted. I still think druids are viable but we're not as strong as before.
I run with as little spirit as possible and I don't have any major mana issues if I use my pot + innervate correctly.
