Why does DDO even bother with Warlocks? Especially using the pacts, and not Invocations. To me, it is a big mistake. Warlocks are Any-Evil alignment. But I suppose, if they can restrict Paladins to Lawful Good, they can get away with whatever alignment changes for Warlock they wish.
I still believe: Why Pact Warlocks? Those are my absolute least favorite.
This below is a True Warlock.
