Well I did cause a lot of my own problems because I tried to play RTW as I had played MTW and STW. I was using ALT click to move groups and it doesn't work all that well. Dragging the line is faster and works every time. The right click for movement is much better than MTW's left click which often caused you to select a new unit unintentionally. I also turned off banners in RTW which makes it harder to identify your units, and banners should be on for MP. I used a speed slowdown mod in SP for a long time which made it harder to get used to the speed in MP, but have stopped using that and play at regular speed in SP all the time now. I still think units move too fast, but I can play it like that. Maybe I'll try RTW/BI again. RTW v1.3 didn't lag much at all when I tried it in 3v3 with large units, and was very playable. The phalanx even worked well.
