Necro spells have unusually high casting costs, because they are balanced to work with the necros ability to regen mana at an increased rate using lich. Lich is balanced to work with the meditate skill. With the changes to med, theres no point in using it most of the time. Why? look at arch lich 65hp for 35 mana a tick. In combat your gaining 35 mana yes, which would seem like ALOT to other classes, but your also losing 65 hp per tick. it's not that great when your going to have to tap it back (inefficent, and justed used all the mana you gained), or take a heavy HP loss to cast 1 more spell (considering at this point most dots are 500+ mana, its gonna take alot of hp). you might as well just throw your dots on a mob and sit there, when wizards mages etc can now just burn stuff down both solo and group and med up faster than any lich line spells has ever been able to (casting the same dot 2-3 times in a row like a nuke isnt gonna help any thats for sure). if the med changes are to stay I hope that necros are somehow rebalanced, it not only puts us behind other casters but screws with the class balance itself
