The importance/popularity of druids depends on your server population dynamics, your play style, and how deep your collective pockets are (or your tank's pockets at least). But I would never relegate them to 'benchwarmer' status.
The potions work better than druids in many ways BUT they have one SERIOUS drawback... THEY COST MONEY. If someone is willing to pour their hard-earned real-life cash into the OneThumb coffers buying health and restoration pots, so be it! You are helping to ensure that the lights stay on around here, but personally, I would take one or two good druids any day over spending my money so frivolously. That being said, I have spent PLENTY of real life cash on this game, but mostly on other goodies.

I imagine that even those people who spend money on potions MUST appreciate being able to conserve some pots for another day whenever there is a druid to assist.
In nodarbs defence, Tea, he simply posed a question to the masses and offered his personal opinion on it, he did not necessarily intend to start a Druid Uprising! LOL
Either way, I say druids are essential to my clan and to a healthy server even if they are underrated - I am not going to suggest which class or classes I would 'bench' in an effort to avert further rioting!!
