I'm sorry for the double post, but this belongs in its own post, because it includes a replay.
After playing some more, I have come to a couple more conclusions. If you are Rohan and are up against Isengard, Gondor or Dwarves, making cavalry is now illogical and inefficient. So this update is a double edged sword, against Rohan and Mordor, your cavalry now dominate, but against any of the other 3 all you can do is spam peasants. Me and my friend just finished doing some extensive testing to see how good the new trample is, with me as Rohan and him as Gondor. Its safe to say any half decent pikes will now instantly kill cavalry. I'll attach the replay below, its very long and includes a lot of testing of what kinds of damage gets inflicted by trampling and damage cavalry receives from trampling.
It also includes a huge battle towards the end, which sticks to the same rules as a skirmish would, even though we were on epic battle mode. We both had 1800 command points worth of troops, who were all fully upgraded and most were max level, and we fought each-other. He slaughtered my entire army and only lost around 3 battalions, showing how weak Rohan melee is late game. However, I then made a huge army of Rohirrim archers, and killed his entire army. The last thing in the replay is a gigantic double siege of both of our bases at once, where I demonstrate just how weak Rohans siege warfare is in both defence and attack. It takes around 30 Onagers to breach Gondors walls, and when he sends bombardment ships to destroy my base there is nothing I can do about it, because Rohan has no wall mounted catapults. A lot of great showcases of things I've been saying on the forums for some time in this replay, I hope the team will find the time to watch it, long as it is
1 final note, Rohan needs some kind of a scout power, they are the only faction to not have this and it hurts them pretty badly late game.
