Enchanter race/DE racial hide

[wholewitt]

Sorry if this is a question that gets asked a lot, forum search pulled up a crap load of results.

I am looking for some race advice on enchanter (for Green). I've read the wiki and was just curious about dark elf's racial hide as it isn't mentioned as significant. Does it only break charm sometimes? Can someone with experience help me decide if it's worth rolling DE for it or not? I currently have a 28 HIE and invising to get full xp on mobs when soloing is very annoying. I'm aware of the Goblin Gazughi Ring and intend on getting one but that is more of a long term goal and even then only provides invis vs animals.

Thanks for you advise!
