So you expect knights to skill for 119 days, 19 hours, 39 minutes, 50 seconds (4 months) and spend another days and farm gold for weapon upgrades to kill dragons in 3 lucky shots, while all other vocations are already hunting dls, hydras, demons? Melee skills ratio should be 600x at this point, and im not entirely sure it'd even the balance.
Edit: Some player claimed he couldn't kill nor even bloodhit a monk with 60+ skills and 37atk weapon, so on top of huge disbalance of vocations, your knight's melee hits have wrong calculations I believe.
