Enchanter charm isn't classic, we all know this

[nicemace]

one thing that needs to be considered is that during classic no one knew wtf was going on. like the skill level and knowledge about the game was minimal. with time people grew to understand the strengths of certain things like charm, once it was obvious how strong things were it started to get nerfed, such as exp from pet kills during POP.

i think you will find charm was strong in classic but we now have people who have 2 DECADES of playing experience and know how to use it to maximum benefit.
