The cavalry reinforcement, while being similar to lotr, isn't unique to that series. Some people might not like it, but I find it to be a cool option. Ridiculing something because it is similar to another is thing is stupid. If it is awesome, then it shouldn't matter. I find it to be a cool option that adds a little interesting factor that you have to take into account.
This showcase is really cool and I can't wait until I can play this game. You guys really know how to make me want to play this game right now.
