Don't be biased beforehand. RTW phalanx formation had issues as well. Overall I think I will prefer MTW2 formation of pike wall for the most part. The trickiest part of MTW2 will be getting skirmishers done better. I didn't really like it in RTW but some of the skirmishers had such long range they could be quite deadly. MTW2 the range is much shorter and the throwing animation is a bit long.
