1. No. Simply because polearm reaches are fucked up, they are slower than two handers and do less damage.
2. I support more diversity for bows, but I think it would be better to balance them in sync with xbows in a more realistic manner. Xbows should be the long range weapons (and not bows), not because of accuracy, but because of shot speed (thus range). But first xbow effectiveness should be more linked to wpf. However, I don't think it's a good idea to do a general buff to bows even more.
3. I posted some ideas over xp and retirement in another thread
4. Well readjusting is not enough, as someone else said, just remove the crushthrough flag for barmaces and long iron maces. For knockdown, my personal opinion is to remove it completly from the game.
5. Slowing down the reload speed, reducing shot speed A LOT (pro javelin throwers using competition gear can't throw like that, and here we have not so trained soldiers throwing mid quality steel and wood weapons with machine gun speed without moving that do better), increasing accuracy a tad for heavy throwing gear, and decreasing it for light (under franciscas).
6. Pure classes are actually dominating... Very few thrower hybrids have any point in throwing, very few melee using xbow have any points in xbow. Just look at scoreboards and ask people around...
Add to this the over-advantage being faster will grant you (either for spam, feints or blocks), since armors are 1/2 of what they were pre patch. The goal of the game is now hitting first.
Even "marginal" wpf differences will determine who dies and who survives.
For me the real problem isn't the current wpf system, it's the skill requirement progression. Each skill level requires the same 3 points of attribute. For me, low skill levels should require less additionnal attribute points than high skill levels. This would allow REAL hybridation.
