@SteamUser - The disparity in STR stats is probably one of his problems, but I think the cause of it is more tied to the level difference. I don't min-max for STR, and I only really have trouble with my CTH when I'm underlevelled.
The Enchanter is actually a pretty powerful class. The trick with them though, is that they are poor damage dealers. You have to use them to control the battle more - using Rain + Blitzbolt, Slow Current, Teleport, Bitter Cold, those kinds of things to disrupt the enemy, to make it easier for your other classes to take care of them. Jahan is an Enchanter, and makes an excellent pairing with another Enchanter and someone who is either a ranged attacker, or has the Lightning Rod talent and is immune to stun.
Now that Rogues have their own skills, they don't get Tactical Retreat, that's part of the Ranger skillset. Tactical Retreat also no longer leaves a smokecloud behind.
