I think rams are over powered and I don't understand why thy can't be beaten with all melee troops. It does not make sense that you need a sword to bring them down. You can bring down a whole city with towers an castles with a few rams and some supporting units if your opponent doesn't have any strong swordsmen. The most promising strategy to counter rams and catapults seem to be using rams too. So you have rams against rams and rams against catapults. That's absurd in my opinion. (By the way, but off topic: since v17 everything depends on wood, that's no improvement in my opinion. In v16 it was up to your strategy, your civ and the phase of the game whether wood or malt where more important)
