Worst armor? Not really. Druids have Bark.
True but thier armor is still about the worst if not tied with mages
Worst DPS? I think Druids with enough high level gear can easily outdps warriors and even some mages.
dps Druids are about the worst. Perhaps they can be a bit better than rangers but much slower off the mark and thier best dps skills do not stack making thier group dps by far the lowest. Similar equipped dps warriors (not tanks) can easily out dps a Druid. Doubly so when we are talking about locking.
Highest Energy Cost - yes
yep
Slowest Leveling Class - debatable, are we talking solo or groups? Even if solo, a druid with high level gear can level faster than other classes. People just like to see big hits and get impatient.
not much of a debate really Druids are the slowest solo leveling class. They have low dps and when they are dps they have trouble tanking when roots fail. It's not a matter of big hits. Group is somewhat irrelevant you don't have to do anything in a group for xp except not die.
Least played and enjoyed class? Meh, it's really about the player. Very few players are really meant to play a healer class. This is true for any MMORPG. Most people, especially young boys who are the typical largest demographic in an MMORPG game likes to hit hard or hit fast. Those who play druids and get to the high levels do enjoy playing healer classes, and they don't even want to play any other class and always pick a priest or cleric type character.
least played is a hard fact. It's right there on the stats page. Least enjoyed? Well I do hear more complaining but it's debatable I guess. Few people complain about how rogues are so hard to level, lock mobs and bosses, and overall are weak.
Druids can certainly use some help and a lot of improvements to make them more interesting to players, but if you don't have the patience to be the healer type, it doesn't matter what they are.
As a warrior tank, there is only one class (with the proper skills) I would balk at attacking in arena. Guess what it is.
Pvp is a small and broken part of the game at this point sadly. It needs more areas and some improvement.
