New gameplay for archers: don't kite any more, but equip a melee weapon, stand ground and fight.
New gameplay for crossbowmen: don't equip so much equipment any more that you are both a good ranged and a decent melee build.
New gameplay for infantry in general: you can't turn and rotate like a helicopter any more when attacking vertically.
New gameplay for horses: you can't use your horse to deal damage or knock down people any more, only use it as a means of transportation to* get to your enemy, attack him and get away again.
If cavalry were gangstas, they used to drive over somebody and shoot him in the process. Now they are forced to do driveby-shootings, to not damage their pimped car.
* to = ride NEXT to him, don't touch him. Group of people? Stay away from them, same rule like for any other class which is outnumbered.
