Meah...
Look at it form a different angle:
1h+Shield has an obvious advantage of having constant protection against multiple enemies, as well as ranged attacks.
Archers and players who focuses on crossbow, have an obvious advantage of inflicting damage without any risk of being hit themselves. ( Do you remember Birdman and Chimp?.. Or Chris? Sorry, but i don't want to see more players like them again
)
Cavalry has their speed and maneuverability.
2h/Polearm users are the only class that is exposed to all types of damage, and has a limited means of protection. They have to have some advantages, right? It is
THE hardest class to master ( no need to argue with that ), so it is only fair to keep them on top of melee "food chain".
As for diversity, it is natural for players to move towards 2h swords - the most challenging and rewarding type of combat in Mount and Blade. Original, top, Grey players - are all 1h+Shield users, and they are still leading scoreboards. Do you really want to buff them?..
I rarely play battles, but on siege servers - archers are still very popular. Crossbows and throwing weapons might need a little buff though
To sum it up - i approve the latest balance changes. It is my personal opinion, so don't burn me with your hate
