Rebalance PVE to where robe farming in blackbolts or rank 40 bows for high end monsters is no longer viable. Currently, it takes 2 people with a robe, rank 40 Blackbolt and reagents to farm most end game monsters (Leenspar Golem, Dark Dragon, Guardians, etc.). Equipment requirements should scale damage with monsters based on tier.

For example (up for tweaking or further discussion)
Very Hard Monster Requires 3 pieces of R50 or greater for 100% damage.
3 pieces "Mastery" level gear or greater = you would do 100% damage.
2 pieces of "Mastery" level gear = You would do 80% damage.
1 piece of "Mastery" level gear = You would do 60% damage
0 "Mastery" gear equipped = 50% damage.
