Yet you're still wrong, for one, max MP5 is 137.5 mp5, and two, it is still useless for druids because you'll have to use Glyph of Rapid Rejuv to get even close to the CD with ease, which is not used for raid healing. Not to mention they are very mana efficient, so they should not really need an mp5 trinket.[COLOR="red"]

You don't understand druid healing much, do you?

Lol. The cooldown is approx. 0.33 seconds, meaning that in one second you will get around 33 mana if you have hots all around. In 5 seconds that should be up to 150ish mp5. Unless you cast one healing spell every 5 seconds.
Edit: the reason they added the tiny internal cd on 11 mana per heal is because druids were getting hundreds of mana per wild growth.

This is actually wrong, the reason they added the internal cooldown was because of Shadow Priests. Vampiric Embrace was counting as a heal for this spell, so every time you did any damage it would proc 5 times, once on yourself and four times on your party. Since this meant you would get five procs on every single DoT tick, direct damage, Mind Flay tick, ect, it basically resulted in infinite mana for the Shadow Priest. They mentioned Shadow Priests in the Blue post explaining that they added the cooldown.

I'm pretty sure druids, like more healers are haste capped in ICC, so even blanketing the raid, you'll get 55 mp5 max from it. Since 1s will be the closest time between each tick for any hots for a druid without rapid rejuv. With it, you can potentially get it, but you need a lot of haste. The other option is waiting between each cast to get an uneven flow of ticks of hots. Now, I do not know the exact mechanics of each a druid has, but getting to the 0.4s CD is nearly impossible, even for a druid, when playing correctly.
