still using at lvl 55 lvl 40 gear, cause i only find crap.
enemy’s kill me in seconds , cause they are getting stronger and stronger. my motivation is going to zero, to play this game 
There are some very usable pieces of gear from venders and some good pieces from faction venders that are available at level 50 as long as you have leveled them up a little bit. The regular vendor items change every time you leave town so you should check them every time. And then there is crafting. At 55 you should have some iron bits/materials to do some crafting. My first character used yellows in certain slots for awhile, so it’s not uncommon.
Try the gear from the Faction Vendors, it’s not great but it’s pretty good.
Try augments and components to fill in resistances. Work a little with devotions and skill distribution.
What is your mastery?
You can always farm bosses so that you have a good chance to get some epic items. And you find a one shot chest, it should drop at least one epic item (blue).
You should have found some usable blue and green gear by level 55. How far into the game have you progressed? And how much of the game are you exploring? It’s generally advised to explore the full map on your first playthrough of Normal/Veteran so that you know where things are and don’t miss anything. Have you geen getting all the devotion shrines and one-shot chests (with a guaranteed blue drop)?
It’s quite possible to beat the game (defeat final boss on Ultimate) using nothing but yellows. It’s very possible that the problem is your build and/or your general inexperience with the game rather than your gear.
I find it hard to believe you’ve found no greens/blues worth using, you may be dismissing some drops out of hand without realizing their worth.
sure i have some blue and green Items, but they are around lvl 35-45. but its so frustrating to play hours and hours and only get crap loot. I need a bit of motivation,like from time to time a better item. the wow i found a better item effect. thats the reason to farming in my opinion.
and why the hell drop 50% of the bosses no loot bubble?
I bought accidentally a ring, then i realized, the shitty ring costs me 200.000. Sorry that is lol.
Bosses like Gutworm and Alkamos guard a supreme chest. Therefore they do not drop a loot orb, too.
