Get to another dungeons and farm for other characters. There are always will be difficulties with DMG art's, but always will be nice sup pieces. Unfortunate pieces send to craft table and try to get pieces for your main DD in team. With that strategy, I get really good pieces in less than a year. Wish u luck and don't forget firstly max talents.
Many players bash wanderer's insufficiencies because they want op or one shot characters but I knew the potential of wanderer beyond that. And man, I am a wanderer main but after watching your video I had a great realization. His potential is on the attack speed. If you fully utilize that well with decent artifacts then you have a great wanderer. I will definitely pull his weapon and upgrade his constellations especially c1 on his next rerun. This all fill the potential of wanderer that I was thinking about. Thanks, man.
I don't know the difference between a low investment and a high investment wanderer because I got lucky and managed to pull his c1 and his weapon, but I can confidently say that he really shines at high investment, with decent artifacts ( between 20 and 30 crit value ) he already is very strong, I can't imagine with higher investment. People who say that wanderer is only about CA spam probably don't have invested in him
