To make the game and classes more balanced I suggest to add attribute requirements to all items. And not only 1 attribute per item, better to have several requirements. This way pplayrs will have to create more well-rounded character. Cause now it is a bit off scale - people tend to increase only 2 major skills with the rare exceptions and are really weak in the other attributes.
For example:
Body Armor - requires 25 str
Boots - str 5, agi - 15
Gloves - str 5, dex 15
Rings - int 10
Hammer - str 20
Sword - str 15, dex 10
Bow - str 10, dex 10, agi 15
This is just an exaple. All the numbers need to be carefully tested in the PvP sandbox. Cheers
