Um this statement is so full of incorrect information it's silly. First necro is great against plants and undead if you can't figure out why you need to relearn playing a caster. Second in the new chain the hardest hitting toughest mobs are not plant or undead they are humans with pretty high fort saves and as such enchantment is the best way of dealing with them. Epic ward does little to affect enchantment and only affects necro on orange nameds.Enchantment and Necro are incredibly lackluster in much of Druid's Deep (plants) and The High Road (undead). Epic Ward is also all over the place in EE. There are a few places where enchantment shines, but not many. Are you stumping for a return to the days when wizards are supposed to be enchant focused, by the way? If you're telling me that Magister is great because I can be enchant focused in it, well, I think you've already lost the battle over how great Magister is.
If you don't want to use enchantment don't but thats like leaving the hammer in the toolbox and grabbing a screwdriver when you need to pound nails in. I use the best tool for the job that's what being a wizard is all about.
Once again the big benefit to the newer content in EE is it has very little spell pen requirement so twisitng in energy burst as well as freeing up points in magister for things like tempest to give dps while still maintaining the benefits of magister makes it clearly the best option for me in this content. If i was still intent on running drow based content on EE regularly then things are different but I have little reason to run that content anymore.
