Everything is endcontent...well yes but really no
A percentage of drops are affected by player level. I can’t tell you the exact percentage, my guess is around 30 to 50% (good days/bad days playing leads me to believe that).
For instance, say ten items drop – you may get 2 level 70s and 8 level 7s, or 5/5, or 7/3, or 3/7 on both levels ends.
