Should the starting hero for Necropolis be chosen randomly?

I voted for a random hero for Necropolis. There are two main reasons.
1. Necropolis is almost always excluded. Therefore, it needs to be weakened. Choosing a random hero weakens the castle.
2. This rule applies to HotA (as well as to Conflux). I want the rules of HotA and HotP to be the same (although they are almost identical).
