Think you aren't keeping in mind is if you are donning IL 130 gear of course it's going to feel easy, you are pretty much a lv 50 in 56-58 gear. Personally I didn't need to replace my il 135 katana til lv 58 so in a sense it's telling me that while I was leveling from 50-58 I was pretty much wielding an insanely powerful weapon.

If you want challenge, then limit the gear you wear, of course the game is going to be easier if you wear stronger gear, just like an rpg gets easier when you find better loot to use against bosses.
