Well, if I may say something about that...

People said that the running speeds of the heavy and light infantry was too fast...

I can agree with the heavy infantry being too fast, I would say a 20-30 % drop in speed is good (not the 50+% they have in RTR)

But the light infantry running speeds are near appropriate no more than a 10% decrease is necessary. The gear on the average light infantryman in RTW is quite light, barely anything at all.

I honestly think all the cavalry and elephant speeds are appropriate, the slowdowns they made in RTR to cavarly speeds was really annoying
