Trying to understand the complaints about DRK

[Tint]

This can easily be fixed by making DA a duration buff and any skill used under it will receive said buff during its duration for 5.0.

it's actually not that easy. so i activate Dark Arts, spend some mana and have now the Dark Arts buff in place for the next couple of seconds. Great! but now i overcap my mana and have no way to dump it since Dark Arts is already active...

to change the giant stream of incoming and outgoing mana the DRK has to handle you have to basically rebuild the whole job from scratch. increasing the mana costs of dark arts or recuding the incoming mana to balance out that you don't use dark arts that often anymore leads to other problems with your aoe attacks and TBN, wich also depend your mana.
