Little late to the game here, but I'll throw in my opinion as well. I played an enchanter all the way up and it was my first raid character on SoD. I've since switched to a wizard for a couple reasons, but still do bot the enchanter on occasion on the raid if needed. I can still do all the things people are saying they do with enchanters while botting a wizard (admittedly, not a huge attention-needing class). Tash, slow (if help is needed on a boss), start giantkining (with tab target set between two PCs being buffed). And just switch back to nuke on wizard, etc while switching back to enchanter to redo GK.
It's not exactly a difficult setup, which means I'd probably be bored out of my mind just playing an enchanter now that every zone we go to (I've seen it pretty much Sepulcher and beyond, probably started prior to that) everything is yellow con or higher, and the few dark blues in the zone (animations or whatever in CoD) are immune to mez.
CC for an enchanter just doesn't happen on a regular basis on raids. Granted, there are a few encounters designed to need an enchanter, but often a necro or bard can fill in as needed since the CC component isn't incredibly hard (Jeremiah's wolves does come to mind as an exception, but only if you screw it up).
The idea of charming on a raid is a good one I think. To be honest, the way the charm spells work now, I'd be hesitant to do it. Tempus was referencing us working on Sadri Malath gate neck the other night in MielechB and I had charmed a light blue froglok to mess around with. It broke charm in about a min using word of command with 305 cha. Granted, I don't have Hidden Power AAs, but I figure what I do have should make me a little more secure in charming something that isn't going to try to eat my face right after I finish buffing it. Obviously, this is an outlier, but the fact that it can happen makes me hesitate and would do so on these traps. I would certainly give it a try, but I could see it turning into "Hang on guys, my pet broke. Can I get a heal?" and making it more a hassle than it is worth.
The proposed suggestion of switching out relic nuke for relic charm as an upgrade to word of command is a good idea. We're pretty much talking just about raid scenarios, and relic spells should be useful on raids. Plinking away with relic nuke, especially after playing a wizard, doesn't seem very effective. It's much more useful to just giantkin, which is something an enchanter without a single relic spell can do.
In summary, I support the change to a relic charm and would be more than willing to give charming a trap-pet a shot, even more so with a more reliable, raid-worthy charm spell to do so with.
