Should we ban the Griffin Conservatory and the Hive of Serpents?

It's a different story when (and this happens too, I think about 20% of the time) one player gets lucky in something, while another gets completely unlucky in everything.

I formed my opinion precisely because I haven't encountered situations where someone is completely unlucky in everything, in about 60 online games. The two worst scenarios I remember were when I was playing as Blue Necropolis and was rushed twice by Elves, but in that case, I apologize, it's the price to pay for the additional bonuses of that faction. Since then, I haven't allowed myself to play Necropolis-Rampart as Blue. In all other cases, losses were the result of mistakes.
