If you need help balancing you can also contact me. Also stay night would probably be better, the servants there are more balanced imo (f/z berserker is fucking absurd).
@Drezi: I meant this specific setup wouldn't work for different-alignment pairs. Some pairs should always be the same alignment though, for example the Berserker pair. No matter which HGW you'd base it on, Berserker should always lose voting ability, which makes him highly dependent on his Master to achieve anything. Whereas a pair like Saber or Archer could do fine with different alignments, since those are always capable of indepedent action.
