I'm not sure who is giving people the idea that enchanters are not a dps toon. That might have been true back at level 90, but anywhere above that (and most especially in TDS) they are quite stout when it comes to DPS.
This is my group so you can see numbers, just some random fights.
Dead Apostle in 46s, 7035k @152932sdps --- Ranger+ pets 1852k@40268sdps (47496dps in 39s) --- Mage+ pets 1820k@39573sdps (56886dps in 32s) --- Enchanter 1497k@32542sdps (33266dps in 45s) --- Wizard 1490k@32384sdps (57295dps in 26s) --- LazyBeastlord 376k@8164sdps (9159dps in 41s)
Notice the chanter did 32kdps.. .he was also tanking. So many of his casts there were runes.
So later that night we did the hero mission in the same zone, replaced the mage with a warrior tank (need to be free to do CC there as the chanter.)
Captain Gurshock in 56s, 9176k @163850sdps --- Enchanter 3913k@69879sdps (81526dps in 48s) --- Ranger 2625k@46869sdps (54681dps in 48s) --- Wizard 1461k@26093sdps (73061dps in 20s) --- LazyBeastlord + pets 740k@13216sdps (13706dps in 54s) --- Warrior + pets 436k@7792sdps (7792dps in 56s)
As you can see, enchanters are not hurting and they are able to keep up with wizards(in the group game, not on raids) if you use twincast mezes consistently. Wizard can easily out parse us in the long run, but they should be able to. Mage can out burn us for a short time, but mages run out of mana pretty fast and NEED to be able to cast rains (which is a messy thing in a box group, as they will break mezzes.)
If I were gong to replace the druid (which I'm not sure I would), I'd definitely go wizard. A wizard has the best synergy with the enchanter of any class out there. Twincast + mana Reverb + IOG + chromatic haze = nukes in the 1million damage range during burns. Druid I think is very powerful, but I'd almost say that I'd learn to heal with the druid and get rid of the cleric for a wizard. (Thought cleric is the best healer hands down.) Druid has a nice synergy with casters as well, and can heal just fine for most content especially with a warrior.
Just a secondary thought, many of the hardest Missions in the game are built around the need to have 2 tanks, and 2 healers. Your current group has two tanks (war + mage pet) and two healers (druid + cleric). Filling in the other two slots with good dps is where I would look the most. Druid does fine for a dps that is also a backup healer. And I can't imagine this group having any trouble whatsoever with content in the game if played right.

This btw is what 3 hours looks like, when comparing classes together.
