Not on NA kafein (thought there was more cav on EU too). Lower server population I usually get off my horse because I actually feel dirty riding around on it. Cavalry and archers seem very overpowered with lower populations, especially when the balance decides to put 12 out of the 15 archers on one team.
It's really bad if you get a group of 5 horse xbow (or archers) all rocking the same banner, they can literally destroy the fun for anyone on the opposite team (because their best counter, is other horse ranged, or ground ranged, and they can easily stay away from ground archers).
The current balance system is fucking terrible, and it's flaws have been pointed out literally 1000's of times since it's inception. But it's here to stay.
if we had a better balance system, then I don't think archers and cavalry would be as heavily nerfed as they have been.
