So it looks like the Devs are having much fun with a goal in mind without communicating what it is. Sure would make for a more productive conversation in a beta program if some idea of what you Devs are trying to achieve was posted along with the changes. Two classes are feeling a nerf, when what apparently is trying to happen is a change in combat balance on the ground.
IF
Archer jumpshot
AND
Cavalry acceleration
is changed
GOOD result.
I can adjust on the ground without needing to jump.
If the cavalry change is reverted, the revert the archery change because the "balancing" didnt work if you have to take back one part of the balancing.
If the cavalry change is reverted so that acceleration on horse is back to normal and the jump is still removed, then return melee athletics acceleration back to near normal.
