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

You'll laugh (lol), but a friend and I played like this: ban on grail, native secondaries, logistics specialists, level 7 dwellings, DD, TP, fly; the 3rd hero at 131, the 4th at 211, because of hotseat. With random maps (oh! the solution!) the ban on cans/hives didn't matter—there were few and they were scattered. Before this, every second game ended in surrender/defeat due to an obvious imbalance, but this way... well, there's less excitement and more work.
