Here's a cross post of something I said in another thread:
By obtaining PVE gear you could progress to tougher and tougher mobs solo. While a group could take it on right away you could to but would have to spend time farming for PVE gear.
In case you haven't played cats, PVE bonuses are
% chance to block
% chance to parry
% chance to evade
Bonus to style damage
Bonus to reactionary style damage
... a few others.
These items are normally obtains in Catacombs, but I hate the idea of leading everyone to a new zone just to get certain gear. Might I suggest that once you hit level 50 the unique items will start to contain PVE bonuses. These bonuses only work against NPC's and only in non rvr zones. The chance of getting PvE bonuses will be minimal, so it will require farming to collect enough gear to make a difference.
The primary goal here is to allow someone who can't group a lot the ability to collect enough gear to be able to tackle the tougher (some, not all) mobs. This gear could only be worn by players of the appropriate level (possibly limited to 50).
Would anyone be interested in this? Would anyone be concerned it might break the balance? Too cheesy? I'm PvE centric so many times my ideas sound loony to others.

Here are some examples of PvE gear:

These are dropped items but these bonuses are also available on unique items.
