For me the problem is you see the game. As a game where people think. oww he is an archer lets kill him. he should not have any melee abilities. I think he should have the same. But the melee on the other end should have the professionalism to fight with diffrent kind of melee weapons. not only with 2 hand.
And also with shield. Because somebody who could afford a armour in medieval times would also have a special training. Because the armour is so expansiv that you can nor risk
it to lose that kind of troops in your army. As an lord.
Archers where special against all kind of mail armored targets. against Plated armored guys you would stand little chance only with your arrows. Maybe you can kill one before he arrives at you with his horse. But then you would get problems.
And longbow archers where also that OP because they always aim for the horses. But when i would be a plated charges. covered in steel as well like the rider. You really think you would do some damage . Seriously ??? there is like a 40 -60 meters killing zone. so you actually have the chance to do one deadly shoot. But then they would ride into you stevve. because it would not only be one rider. like HESKEYTIME said you would be protected by melees as well . What forms a professional army. makes a rubble to man. And not like lets make World of warcraft mod out of this shit.
