I seem to think that Rogues/Druids make the best enchanters, as they make the best Disenchanters. Not that it is a better enchanter, but it is much eazer if you can solo in to say, Gnomer all stealthed up and kill Viscous Fallout for a shard every 5-10 min, or even SM for higher level shards.
once again not better enchanters, but mats are eazy to come by for those that can stealth.
