Many loot tables on (X) heroic mobs have been linked since you outlevel zones to fast even with normal xp and the basic idea is to gear up while you go so when you reach lvl 51 your decently geared up to tackle the content to come and not have x item be completely underpowered when you get up there. Also drop rates in higher lvl dungeons are higher drop % then the lower level dungeons so its prolly a bad streak.
That said, PoF has an even higher drop % due to many classes having their gear drop there but if you go solo killling stuff will be slower then when you group or duo it.
I also would like to say that at this moment itemizations is 20% done and all the dungeons named when done will drop their own loot again instead of the current linked table we have now.
I just have to put priorities into what i work on atm and i could also just lock the server but i find it a waste to do that.
So while the server moves on into development quite allot of things will improve
The Server will allow for incredible player power along the road but it won't become one that instantly gives everything away.
