Reduce damage reduction from mob levels

IMO it is a bit silly to see SS PD tanking 4+ Demons in a HP set with one pa piece  and a MA.

I would suggest the ceiling is lowered and formula changed to give much less as the levels go higher (say above lvl 40) for tier 7/8.

If the reduction stuffs up hunting, it could always be changed back. 

If you have different suggestions please make them in the comments
